 # NaviDocs OCR Pipeline - Complete Setup Guide
 ## Overview
 The OCR pipeline has been successfully implemented with three core components:
 1. **OCR Service** (`server/services/ocr.js`) - PDF to text extraction using Tesseract.js
 2. **Search Service** (`server/services/search.js`) - Meilisearch indexing with full metadata
 3. **OCR Worker** (`server/workers/ocr-worker.js`) - BullMQ background job processor

 ## API Usage
 ### Creating an OCR Job
 ```javascript
 import { v4 as uuidv4 } from 'uuid';
 import { addOcrJob } from './services/queue.js';
 import { getDb } from './config/db.js';
 // 1. Create document record
 const documentId = uuidv4();
 const db = getDb();
 db.prepare(`
  INSERT INTO documents (
    id, organization_id, entity_id, uploaded_by,
    title, file_path, status, created_at, updated_at
  ) VALUES (?, ?, ?, ?, ?, ?, 'processing', ?, ?)
 `).run(
  documentId,
  organizationId,
  boatId,
  userId,
  'Boat Manual',
  '/uploads/manual.pdf',
  Date.now() / 1000,
  Date.now() / 1000
 );
 // 2. Create OCR job
 const jobId = uuidv4();
 db.prepare(`
  INSERT INTO ocr_jobs (id, document_id, status, created_at)
  VALUES (?, ?, 'pending', ?)
 `).run(jobId, documentId, Date.now() / 1000);
 // 3. Queue for processing
 await addOcrJob(documentId, jobId, {
  filePath: '/uploads/manual.pdf'
 });
 console.log(`Job ${jobId} queued for document ${documentId}`);
 ```
 ### Monitoring Progress
 ```javascript
 import { getDb } from './config/db.js';
 // Check database status
 const job = db.prepare(`
  SELECT status, progress, error FROM ocr_jobs WHERE id = ?
 `).get(jobId);
 console.log(`Status: ${job.status}`);
 console.log(`Progress: ${job.progress}%`);
 // Poll for completion
 const pollInterval = setInterval(() => {
  const updated = db.prepare(`
    SELECT status, progress FROM ocr_jobs WHERE id = ?
  `).get(jobId);
  if (updated.status === 'completed') {
    clearInterval(pollInterval);
    console.log('OCR complete!');
  } else if (updated.status === 'failed') {
    clearInterval(pollInterval);
    console.error('OCR failed:', updated.error);
  }
 }, 2000);
 ```
 ### Searching Indexed Content
 ```javascript
 import { searchPages } from './services/search.js';
 // Basic search
 const results = await searchPages('bilge pump maintenance', {
  limit: 20
 });
 // User-specific search
 const userResults = await searchPages('electrical system', {
  filter: `userId = "${userId}"`,
  limit: 10
 });
 // Organization search
 const orgResults = await searchPages('generator', {
  filter: `organizationId = "${orgId}"`,
  sort: ['pageNumber:asc']
 });
 // Advanced filtering
 const filtered = await searchPages('pump', {
  filter: [
    'vertical = "boating"',
    'systems IN ["plumbing"]',
    'ocrConfidence > 0.8'
  ].join(' AND '),
  limit: 10
 });
 // Process results
 results.hits.forEach(hit => {
  console.log(`Page ${hit.pageNumber}: ${hit.title}`);
  console.log(`Boat: ${hit.boatName} (${hit.boatMake} ${hit.boatModel})`);
  console.log(`Confidence: ${(hit.ocrConfidence * 100).toFixed(0)}%`);
  console.log(`Text: ${hit.text.substring(0, 200)}...`);
 });
 ```
 ## Database Schema
 ### ocr_jobs Table
 ```sql
 CREATE TABLE ocr_jobs (
  id TEXT PRIMARY KEY,              -- Job UUID
  document_id TEXT NOT NULL,        -- Reference to documents table
  status TEXT DEFAULT 'pending',    -- pending | processing | completed | failed
  progress INTEGER DEFAULT 0,       -- 0-100 percentage
  error TEXT,                       -- Error message if failed
  started_at INTEGER,               -- Unix timestamp
  completed_at INTEGER,             -- Unix timestamp
  created_at INTEGER NOT NULL,
  FOREIGN KEY (document_id) REFERENCES documents(id) ON DELETE CASCADE
 );
 ```
 ### document_pages Table
 ```sql
 CREATE TABLE document_pages (
  id TEXT PRIMARY KEY,              -- Page UUID
  document_id TEXT NOT NULL,
  page_number INTEGER NOT NULL,
  -- OCR data
  ocr_text TEXT,                    -- Extracted text
  ocr_confidence REAL,              -- 0.0 to 1.0
  ocr_language TEXT DEFAULT 'en',
  ocr_completed_at INTEGER,
  -- Search indexing
  search_indexed_at INTEGER,
  meilisearch_id TEXT,              -- ID in Meilisearch
  metadata TEXT,                    -- JSON
  created_at INTEGER NOT NULL,
  UNIQUE(document_id, page_number),
  FOREIGN KEY (document_id) REFERENCES documents(id) ON DELETE CASCADE
 );
 ```
 ## Meilisearch Document Structure
 Each indexed page contains:
 ```json
 {
  "id": "page_doc123_p7",
  "vertical": "boating",
  "organizationId": "org_xyz",
  "organizationName": "Smith Family Boats",
  "entityId": "boat_abc",
  "entityName": "Sea Breeze",
  "entityType": "boat",
  "docId": "doc123",
  "userId": "user456",
  "documentType": "component-manual",
  "title": "8.7 Blackwater System",
  "pageNumber": 7,
  "text": "The blackwater pump is located...",
  "systems": ["plumbing", "waste-management"],
  "categories": ["maintenance", "troubleshooting"],
  "tags": ["pump", "blackwater"],
  "boatName": "Sea Breeze",
  "boatMake": "Prestige",
  "boatModel": "F4.9",
  "boatYear": 2024,
  "vesselType": "powerboat",
  "language": "en",
  "ocrConfidence": 0.94,
  "createdAt": 1740234567,
  "updatedAt": 1740234567
 }
 ```
 ## Worker Behavior
 The OCR worker:
 1. **Processes jobs from 'ocr-jobs' queue**
 2. **Updates progress** in database (0-100%)
 3. **For each page:**
   - Converts PDF page to image (300 DPI PNG)
   - Runs Tesseract OCR
   - Saves text to `document_pages` table
   - Indexes in Meilisearch with full metadata
 4. **On completion:**
   - Updates document status to 'indexed'
   - Marks job as completed
 5. **On failure:**
   - Updates job status to 'failed'
   - Stores error message
   - Updates document status to 'failed'
 ### Worker Configuration
 ```javascript
 // In ocr-worker.js
 const worker = new Worker('ocr-jobs', processOCRJob, {
  connection,
  concurrency: 2,        // Process 2 documents simultaneously
  limiter: {
    max: 5,              // Max 5 jobs
    duration: 60000      // Per minute
  }
 });
 ```
 ## Performance Benchmarks
 ### Processing Times
 - **Small PDF** (10 pages): 30-60 seconds
 - **Medium PDF** (50 pages): 2-5 minutes
 - **Large PDF** (200 pages): 10-20 minutes
 ### Resource Usage
 - **Memory**: ~50-100 MB per worker
 - **CPU**: Moderate (Tesseract OCR is CPU-intensive)
 - **Disk**: Temporary images cleaned up automatically
 ### Search Performance
 - **Indexing**: 10-50ms per page
 - **Search**: <50ms for typical queries
 - **Index Size**: ~1-2 KB per page
 ## Troubleshooting
 ### PDF Conversion Fails
 ```bash
 # Check available tools
 node -e "import('./services/ocr.js').then(m => console.log(m.checkPDFTools()))"
 # Install missing tools
 sudo apt-get install poppler-utils imagemagick
 ```
 ### Tesseract Not Found
 ```bash

    image: getmeili/meilisearch:latest
    ports:
      - "7700:7700"
    environment:
      MEILI_MASTER_KEY: ${MEILISEARCH_MASTER_KEY}
    volumes:
      - meilisearch-data:/data.ms
  ocr-worker:
    build: .
    command: node workers/ocr-worker.js
    environment:
      REDIS_HOST: redis
      MEILISEARCH_HOST: http://meilisearch:7700
      OCR_CONCURRENCY: 2
    depends_on:
      - redis
      - meilisearch
    volumes:
      - ./uploads:/app/uploads
 volumes:
  redis-data:
  meilisearch-data:
 ```
 ### Environment Variables
 ```bash
 # Required
 DATABASE_PATH=/data/navidocs.db

  -e MEILI_MASTER_KEY=masterKey \
  getmeili/meilisearch:latest
 ```
 ## 3. Configure Environment
 ```bash
 cd server
 cat > .env << EOF
 DATABASE_PATH=./db/navidocs.db
 REDIS_HOST=127.0.0.1
 REDIS_PORT=6379
 MEILISEARCH_HOST=http://127.0.0.1:7700
 MEILISEARCH_MASTER_KEY=masterKey
 OCR_CONCURRENCY=2
 EOF
 ```
 ## 4. Initialize Database
 ```bash
 node db/init.js
 ```
 ## 5. Start OCR Worker
 ```bash
 # Terminal 1: Start worker
 node workers/ocr-worker.js
 # Terminal 2: Start API server
 npm start
 ```
 ## 6. Test the Pipeline
 ```bash
 # Verify setup
 node scripts/test-ocr.js
 # Run examples
 node examples/ocr-integration.js
 ```
 ## Usage Example
 ```javascript
 import { v4 as uuidv4 } from 'uuid';
 import { addOcrJob } from './services/queue.js';
 import { getDb } from './config/db.js';
 // Create document
 const documentId = uuidv4();
 const jobId = uuidv4();
 const db = getDb();
 db.prepare(`
  INSERT INTO documents (id, organization_id, uploaded_by, title, file_path, status, created_at, updated_at)
  VALUES (?, ?, ?, ?, ?, 'processing', ?, ?)
 `).run(documentId, 'org123', 'user456', 'Boat Manual', '/uploads/manual.pdf', Date.now()/1000, Date.now()/1000);
 // Create OCR job
 db.prepare(`
  INSERT INTO ocr_jobs (id, document_id, status, created_at)
  VALUES (?, ?, 'pending', ?)
 `).run(jobId, documentId, Date.now()/1000);
 // Queue for processing
 await addOcrJob(documentId, jobId, { filePath: '/uploads/manual.pdf' });
 // Monitor progress
 setInterval(() => {
  const job = db.prepare('SELECT status, progress FROM ocr_jobs WHERE id = ?').get(jobId);
  console.log(`${job.status}: ${job.progress}%`);
 }, 2000);
 ```
 ## Search Example
 ```javascript
 import { searchPages } from './services/search.js';
 const results = await searchPages('bilge pump maintenance', {
  filter: `userId = "user123"`,
  limit: 10
 });
 results.hits.forEach(hit => {
  console.log(`Page ${hit.pageNumber}: ${hit.title}`);
  console.log(`Confidence: ${(hit.ocrConfidence * 100).toFixed(0)}%`);
 });
 ```

 # lilian1 (FRANK-AI) Code Extraction Plan
 **Date:** 2025-10-19
 **Purpose:** Extract clean, production-ready code from lilian1 prototype; discard experimental Frank-AI features
 **Target:** NaviDocs MVP with Meilisearch-inspired design
 ---
 ## Executive Summary
 lilian1 is a working boat manual assistant prototype called "FRANK-AI" with:
 - **Total size:** 2794 lines of JavaScript (7 files)
 - **Clean code:** ~940 lines worth extracting
 - **Frank-AI junk:** ~1850 lines to discard
 - **Documentation:** 56+ experimental markdown files to discard
 ### Key Decision: What to Extract vs Discard
 | Category | Extract | Discard | Reason |
 |----------|---------|---------|--------|
 | Manual management | ✅ | | Core upload/job polling logic is solid |
 | Figure zoom | ✅ | | Excellent UX, accessibility-first, production-ready |
 | Service worker | ✅ | | PWA pattern is valuable for offline boat manuals |
 | Quiz system | | ❌ | Gamification - not in NaviDocs MVP scope |
 | Persona system | | ❌ | AI personality - not needed |
 | Gamification | | ❌ | Points/achievements - not in MVP scope |
 | Debug overlay | | ❌ | Development tool - replace with proper logging |
 ---
 ## Files to Extract
 ### 1. app/js/manuals.js (451 lines)
 **What it does:**
 - Upload PDF to backend
 - Poll job status with progress tracking
 - Catalog loading (manuals list)
 - Modal controls for upload UI
 - Toast notifications
 **Clean patterns to port to Vue:**
 ```javascript
 // Job polling pattern (lines 288-322)
 async function startPolling(jobId) {
  pollInterval = setInterval(async () => {
    const response = await fetch(`${apiBase}/api/manuals/jobs/${jobId}`);
    const data = await response.json();
    updateJobStatus(data);
    if (data.status === 'completed' || data.status === 'failed') {
      clearInterval(pollInterval);
    }
  }, 2000);
 }
 ```
 **Port to NaviDocs as:**
 - `client/src/components/UploadModal.vue` - Upload UI
 - `client/src/composables/useJobPolling.js` - Polling logic
 - `client/src/composables/useManualsCatalog.js` - Catalog state
 **Discard:**
 - Line 184: `ingestFromUrl()` - Claude CLI integration (not in MVP)
 - Line 134: `findManuals()` - Claude search (replace with Meilisearch)
 ---
 ### 2. app/js/figure-zoom.js (299 lines)
 **What it does:**
 - Pan/zoom for PDF page images
 - Mouse wheel, drag, touch pinch controls
 - Keyboard shortcuts (+, -, 0)
 - Accessibility (aria-labels, prefers-reduced-motion)
 - Premium UX (spring easing)
 **This is EXCELLENT code - port as-is to Vue:**
 - `client/src/components/FigureZoom.vue` - Wrap in Vue component
 - Keep all logic: updateTransform, bindMouseEvents, bindTouchEvents
 - Keep accessibility features
 **Why it's good:**
 - Respects `prefers-reduced-motion`
 - Proper event cleanup
 - Touch support for mobile
 - Smooth animations with cubic-bezier easing
 ---
 ### 3. app/service-worker.js (192 lines)
 **What it does:**
 - PWA offline caching
 - Precache critical files (index.html, CSS, JS, data files)
 - Cache-first strategy for data, network-first for HTML
 - Background sync hooks (future)
 - Push notification hooks (future)
 **Port to NaviDocs as:**
 - `client/public/service-worker.js` - Adapt for Vue/Vite build
 - Update PRECACHE_URLS to match Vite build output
 - Keep cache-first strategy for manuals (important for boats with poor connectivity)
 **Changes needed:**
 ```javascript
 // OLD: FRANK-AI hardcoded paths
 const PRECACHE_URLS = ['/index.html', '/css/app.css', ...];
 // NEW: Vite build output (generated from manifest)
 const PRECACHE_URLS = [
  '/',
  '/assets/index-[hash].js',
  '/assets/index-[hash].css',
  '/data/manuals.json'
 ];
 ```
 ---
 ### 4. data/glossary.json (184 lines)
 **What it is:**
 - Boat manual terminology index
 - Maps terms to page numbers
 - Examples: "Bilge", "Blackwater", "Windlass", "Galley", "Seacock"
 **How to use:**
 - Extract unique terms
 - Add to Meilisearch synonyms config (we already have 40+, this adds more)
 - Use for autocomplete suggestions in search bar
 **Example extraction:**
 ```javascript
 // Terms we don't have yet in meilisearch-config.json:
 "seacock": ["through-hull", "thru-hull"],  // ✅ Already have
 "demister": ["defroster", "windscreen demister"],  // ➕ Add
 "reboarding": ["ladder", "swim platform"],  // ➕ Add
 "mooring": ["docking", "tie-up"],  // ➕ Add
 ```
 ---
 ## Files to Discard
 ### Gamification / AI Persona (Frank-AI Experiments)
 | File | Lines | Reason to Discard |
 |------|-------|-------------------|
 | app/js/quiz.js | 209 | Quiz game - not in MVP scope |
 | app/js/persona.js | 209 | AI personality system - not needed |
 | app/js/gamification.js | 304 | Points/badges/achievements - not in MVP |
 | app/js/debug-overlay.js | ~100 | Dev tool - replace with proper logging |
 **Total discarded:** ~820 lines
 ---
 ### Documentation Files (56+ files to discard)
 All files starting with:
 - `CLAUDE_SUPERPROMPT_*.md` (8 files) - AI experiment prompts
 - `FRANK_AI_*.md` (3 files) - Frank-AI specific docs
 - `FIGURE_*.md` (6 files) - Figure implementation docs (interesting but not needed)
 - `TEST_*.md` (8 files) - Test reports (good to read, but don't copy)
 - `*_REPORT.md` (12 files) - Sprint reports
 - `*_SUMMARY.md` (10 files) - Session summaries
 - `SECURITY-*.md` (3 files) - Security audits (good insights, already captured in hardened-production-guide.md)
 - `UX-*.md` (3 files) - UX reviews
 **Keep for reference (read but don't copy):**
 - `README.md` - Understand the project
 - `CHANGES.md` - What was changed over time
 - `DEMO_ACCESS.txt` - How to run lilian1
 **Total:** ~1200 lines of markdown to discard
 ---
 ## Migration Strategy

 cd ~/navidocs
 # Create directories
 mkdir -p server/{routes,services,workers,db,config}
 mkdir -p client/{src/{components,composables,views,stores,assets},public}
 # Initialize package.json files
 ```

    "postcss": "^8.4.0"
  }
 }
 ```
 ---
 ### Phase 2: Port Clean Code
 #### Step 1: Figure Zoom Component
 **From:** lilian1/app/js/figure-zoom.js
 **To:** navidocs/client/src/components/FigureZoom.vue
 **Changes:**
 - Wrap in Vue component
 - Use Vue refs for state (`scale`, `translateX`, `translateY`)
 - Use Vue lifecycle hooks (`onMounted`, `onUnmounted`)
 - Keep all UX logic identical
 **Implementation:**
 ```vue
 <template>
  <div class="figure-lightbox" v-if="isOpen">
    <img
      ref="imageRef"
      :src="imageSrc"
      @wheel="handleWheel"
      @mousedown="handleMouseDown"
    />
    <div class="zoom-controls">
      <button @click="zoomIn">+</button>
      <button @click="zoomOut">−</button>
      <button @click="reset">⟲</button>
      <span>{{ Math.round(scale * 100) }}%</span>
    </div>
  </div>
 </template>
 <script setup>
 import { ref, onMounted, onUnmounted } from 'vue';
 const imageRef = ref(null);
 const scale = ref(1);
 const translateX = ref(0);
 const translateY = ref(0);
 // Copy all logic from figure-zoom.js
 // ...
 </script>
 ```
 #### Step 2: Upload Modal Component
 **From:** lilian1/app/js/manuals.js (lines 228-263)
 **To:** navidocs/client/src/components/UploadModal.vue
 **Changes:**
 - Replace vanilla DOM manipulation with Vue reactivity
 - Use `<script setup>` syntax
 - Replace FormData upload with Meilisearch-safe approach
 #### Step 3: Job Polling Composable
 **From:** lilian1/app/js/manuals.js (lines 288-322)
 **To:** navidocs/client/src/composables/useJobPolling.js
 **Pattern:**
 ```javascript
 import { ref, onUnmounted } from 'vue';
 export function useJobPolling(apiBase) {
  const jobId = ref(null);
  const progress = ref(0);
  const status = ref('pending');
  let pollInterval = null;
  async function startPolling(id) {
    jobId.value = id;
    pollInterval = setInterval(async () => {
      const response = await fetch(`${apiBase}/api/jobs/${id}`);
      const data = await response.json();
      progress.value = data.progress;
      status.value = data.status;
      if (data.status === 'completed' || data.status === 'failed') {
        clearInterval(pollInterval);
      }
    }, 2000);
  }
  onUnmounted(() => {
    if (pollInterval) clearInterval(pollInterval);
  });
  return { jobId, progress, status, startPolling };
 }
 ```
 #### Step 4: Service Worker
 **From:** lilian1/app/service-worker.js
 **To:** navidocs/client/public/service-worker.js
 **Changes:**
 - Update CACHE_NAME to `navidocs-v1`
 - Update PRECACHE_URLS to match Vite build output
 - Keep cache strategy identical (cache-first for data, network-first for HTML)
 ---
 ### Phase 3: Backend API Structure
 **New files (not in lilian1):**
 ```
 server/
 ├── index.js              # Express app entry point
 ├── config/
 │   └── db.js             # SQLite connection

 └── db/
    └── schema.sql        # (Already created in docs/architecture/)
    └── migrations/       # Future schema changes
 ```
 **Lilian1 had:** `api/server.js` (custom search logic)
 **NaviDocs will use:** Meilisearch (< 10ms vs ~100ms, typo tolerance, synonyms)

 ## Design System: Meilisearch-Inspired
 **User directive:** "use as much of the https://www.meilisearch.com/ look and feel as possible, grab it all, no emojis, clean svg sybold for an expensive grown up look and feel"
 ### Visual Analysis of Meilisearch.com
 **Colors:**
 - Primary: `#FF5CAA` (Pink)
 - Secondary: `#6C5CE7` (Purple)
 - Accent: `#00D4FF` (Cyan)
 - Neutral: `#1E1E2F` (Dark), `#F5F5FA` (Light)
 **Typography:**
 - Headings: Bold, sans-serif (likely Inter or similar)
 - Body: Medium weight, generous line-height
 - Code: Monospace (Fira Code or similar)
 **Icons:**
 - Clean SVG line icons
 - 24px base size
 - 2px stroke weight
 - Rounded corners (not sharp)
 **Components:**
 - Generous padding (24px, 32px)
 - Subtle shadows: `box-shadow: 0 4px 24px rgba(0,0,0,0.08)`
 - Rounded corners: `border-radius: 12px`
 - Search bar: Large (56px height), prominent, centered
 **NaviDocs adaptation:**
 ```css
 /* Tailwind config */
 {
  colors: {
    primary: '#0EA5E9',      // Sky blue (boat theme)
    secondary: '#6366F1',    // Indigo
    accent: '#10B981',       // Green (success)
    dark: '#1E293B',
    light: '#F8FAFC'
  },
  fontFamily: {
    sans: ['Inter', 'system-ui', 'sans-serif'],
    mono: ['Fira Code', 'monospace']
  },
  borderRadius: {
    DEFAULT: '12px',
    lg: '16px'
  }
 }
 ```
 ### Icon System
 **NO emojis** - Use clean SVG icons from:
 - Heroicons (MIT license) - https://heroicons.com/
 - Lucide (ISC license) - https://lucide.dev/
 **Icons needed:**
 - Upload (cloud-arrow-up)
 - Search (magnifying-glass)
 - Document (document-text)
 - Boat (custom or use sailboat icon)
 - Settings (cog)
 - User (user-circle)
 - Close (x-mark)
 - Zoom in/out (magnifying-glass-plus/minus)
 ---
 ## Data Structure Insights
 ### lilian1 data/pages.json structure:
 ```json
 {
  "manual": "boat",
  "slug": "boat",
  "vendor": "Prestige",
  "model": "F4.9",
  "pages": [
    {
      "p": 1,
      "headings": ["Owner Manual", "Technical Information"],
      "text": "Full OCR text here...",
      "figures": ["f1-p42-electrical-overview"]
    }
  ]
 }
 ```
 ### NaviDocs Meilisearch document structure:
 ```json
 {
  "id": "page_doc_abc123_p7",
  "vertical": "boating",
  "organizationId": "org_xyz789",
  "entityId": "boat_prestige_f49_001",
  "entityName": "Sea Breeze",
  "docId": "doc_abc123",
  "userId": "user_456",
  "documentType": "owner-manual",
  "title": "Owner Manual - Page 7",
  "pageNumber": 7,
  "text": "Full OCR text here...",
  "boatMake": "Prestige",
  "boatModel": "F4.9",
  "boatYear": 2024,
  "language": "en",
  "ocrConfidence": 0.94,
  "createdAt": 1740234567,
  "updatedAt": 1740234567
 }
 ```
 **Key difference:** NaviDocs uses **per-page documents** in Meilisearch (same as lilian1), but with richer metadata for multi-vertical support.
 ---
 ## Testing Strategy
 ### lilian1 had:
 - Playwright E2E tests (tests/e2e/app.spec.js)
 - Multi-manual ingestion tests
 - Engagement pack tests
 ### NaviDocs will have:
 **Playwright tests:**
 ```
 tests/
 ├── upload.spec.js        # Upload PDF → job completes → searchable
 ├── search.spec.js        # Search with synonyms
 ├── document.spec.js      # View PDF, zoom figures
 └── offline.spec.js       # PWA offline mode
 ```
 **Test cases:**
 1. Upload PDF → OCR completes in < 5min → search finds text
 2. Search "bilge" → finds "sump pump" (synonym test)
 3. Search "electrical" → highlights matches in results
 4. Open document → zoom in/out → pan around
 5. Go offline → app still loads → cached manuals work
 ---
 ## Success Criteria
 **Before declaring NaviDocs MVP ready:**
 - [ ] All clean code extracted from lilian1
 - [ ] No Frank-AI junk (quiz, persona, gamification) in codebase
 - [ ] Meilisearch-inspired design applied (no emojis, clean SVG icons)
 - [ ] Upload PDF → OCR → searchable in < 5min
 - [ ] Search latency < 100ms
 - [ ] Synonym search works ("bilge" finds "sump pump")
 - [ ] Figure zoom component works (pan, zoom, keyboard shortcuts)
 - [ ] PWA offline mode caches manuals
 - [ ] Playwright tests pass (4+ E2E scenarios)
 - [ ] All fields display correctly in UI
 - [ ] No console errors in production build
 - [ ] Proof of working system (screenshots, demo video)

 ## Timeline Estimate
 | Phase | Tasks | Time |
 |-------|-------|------|
 | Bootstrap | Create directory structure, package.json files | 1 hour |
 | Backend API | SQLite schema, Meilisearch setup, upload endpoint | 4 hours |
 | OCR Pipeline | Tesseract.js integration, BullMQ queue | 3 hours |
 | Frontend Core | Vue 3 + Vite + Tailwind setup, routing | 2 hours |
 | Components | Upload modal, search bar, document viewer | 4 hours |
 | Figure Zoom | Port from lilian1, adapt to Vue | 2 hours |
 | Service Worker | Port PWA offline support | 1 hour |
 | Testing | Playwright E2E tests | 3 hours |
 | Polish | Debug, validate fields, UI refinement | 4 hours |
 | **Total** | | **24 hours** |
 **With multi-agent approach:** Can parallelize backend + frontend work → ~12-16 hours
 ---
 ## Next Steps
 1. ✅ Complete this extraction plan document
 2. ⏭️ Bootstrap NaviDocs directory structure
 3. ⏭️ Set up Vue 3 + Vite + Tailwind
 4. ⏭️ Implement backend API (Express, SQLite, Meilisearch)
 5. ⏭️ Port figure-zoom component
 6. ⏭️ Implement upload & OCR pipeline
 7. ⏭️ Add Playwright tests
 8. ⏭️ Debug and validate

 ## Security Implementation
 ### File Validation (file-safety.js)
 1. **Extension Check**: Only `.pdf` allowed
 2. **MIME Type Verification**: Magic number detection via `file-type` package
 3. **Size Limit**: 50MB default (configurable)
 4. **Filename Sanitization**:
   - Path separator removal
   - Null byte removal
   - Special character filtering
   - Length limiting (200 chars)
 ### Access Control
 1. **JWT Authentication**: All routes require valid JWT token
 2. **Organization-Based**: Users can only access documents in their organizations
 3. **Document Ownership**: Uploader has full access
 4. **Share Permissions**: Granular sharing via `document_shares` table
 5. **Role-Based**: Admin/manager roles for deletion
 ### Database Security
 1. **Prepared Statements**: All queries use parameterized queries
 2. **Foreign Keys**: Enforced referential integrity
 3. **Soft Deletes**: Documents marked as deleted, not removed
 4. **Hash Deduplication**: SHA256 hash prevents duplicate uploads
 ### Search Security
 1. **Tenant Tokens**: Scoped to user + organizations
 2. **Row-Level Security**: Filter injection at token generation
 3. **Time-Limited**: 1-hour default, 24-hour maximum
 4. **Client-Side Search**: Direct Meilisearch access with scoped token
 ## Database Schema Integration
 ### Tables Used
 - `documents` - Document metadata and file info
 - `document_pages` - OCR results per page
 - `ocr_jobs` - Background job tracking
 - `users` - User authentication
 - `organizations` - Multi-tenancy
 - `user_organizations` - Membership and roles
 - `entities` - Boats, marinas, condos
 - `components` - Equipment and systems
 - `document_shares` - Sharing permissions
 ### Key Fields
 - All IDs are UUIDs (TEXT in SQLite)
 - Timestamps are Unix timestamps (INTEGER)
 - Metadata fields are JSON (TEXT)
 - Status fields use enums (TEXT with constraints)
 ## Dependencies
 ### Required Services
 - **SQLite**: Database (via better-sqlite3)
 - **Meilisearch**: Search engine (port 7700)
 - **Redis**: Job queue backend (port 6379)
 ### NPM Packages
 - `express` - Web framework
 - `multer` - File upload handling
 - `file-type` - MIME type detection
 - `uuid` - UUID generation
 - `bullmq` - Job queue
 - `ioredis` - Redis client

 -- 4. Add proper CHECK constraints
 -- 5. Consider partitioning for large tables (document_pages)
 -- 6. Add pgvector extension for embedding support

 # NaviDocs API Routes
 This directory contains the backend API route modules for NaviDocs server.
 ## Route Modules
 ### 1. Upload Route (`upload.js`)
 **Endpoint:** `POST /api/upload`
 Handles PDF file uploads with validation, storage, and OCR queue processing.
 **Request:**
 - Content-Type: `multipart/form-data`
 - Body:
  - `file`: PDF file (max 50MB)
  - `title`: Document title (string, required)
  - `documentType`: Document type (string, required)
    - Values: `owner-manual`, `component-manual`, `service-record`, etc.
  - `organizationId`: Organization UUID (string, required)
  - `entityId`: Entity UUID (string, optional)
  - `subEntityId`: Sub-entity UUID (string, optional)
  - `componentId`: Component UUID (string, optional)
 **Response:**
 ```json
 {
  "jobId": "uuid",
  "documentId": "uuid",
  "message": "File uploaded successfully and queued for processing"
 }
 ```
 **Status Codes:**
 - `201`: Created - File uploaded successfully
 - `400`: Bad Request - Invalid file or missing fields
 - `401`: Unauthorized - Authentication required
 - `500`: Internal Server Error
 **Security:**
 - File extension validation (.pdf only)
 - MIME type verification (magic number detection)
 - File size limit (50MB default)
 - Filename sanitization
 - SHA256 hash for deduplication
 ---
 ### 2. Jobs Route (`jobs.js`)
 **Endpoints:**
 #### Get Job Status
 `GET /api/jobs/:id`
 Query OCR job status and progress.
 **Response:**
 ```json
 {
  "jobId": "uuid",
  "documentId": "uuid",
  "status": "pending|processing|completed|failed",
  "progress": 0-100,
  "error": "error message or null",
  "startedAt": timestamp,
  "completedAt": timestamp,
  "createdAt": timestamp,
  "document": {
    "id": "uuid",
    "status": "processing|indexed|failed",
    "pageCount": 42
  }
 }
 ```
 #### List Jobs
 `GET /api/jobs`
 List jobs with optional filtering.
 **Query Parameters:**
 - `status`: Filter by status (`pending`, `processing`, `completed`, `failed`)
 - `limit`: Results per page (default: 50, max: 100)
 - `offset`: Pagination offset (default: 0)
 **Response:**
 ```json
 {
  "jobs": [
    {
      "jobId": "uuid",
      "documentId": "uuid",
      "documentTitle": "Owner Manual",
      "documentType": "owner-manual",
      "status": "completed",
      "progress": 100,
      "error": null,
      "startedAt": timestamp,
      "completedAt": timestamp,
      "createdAt": timestamp
    }
  ],
  "pagination": {
    "limit": 50,
    "offset": 0
  }
 }
 ```
 **Status Codes:**
 - `200`: OK
 - `400`: Bad Request - Invalid job ID
 - `401`: Unauthorized
 - `404`: Not Found - Job not found
 ---
 ### 3. Search Route (`search.js`)
 **Endpoints:**
 #### Generate Tenant Token
 `POST /api/search/token`
 Generate Meilisearch tenant token for client-side search with 1-hour TTL.
 **Request Body:**
 ```json
 {
  "expiresIn": 3600
 }
 ```
 **Response:**
 ```json
 {
  "token": "tenant-token-string",

  "indexName": "navidocs-pages",
  "searchUrl": "http://127.0.0.1:7700"
 }
 ```
 **Security:**
 - Token scoped to user's organizations
 - Row-level security via filters
 - Maximum expiration: 24 hours
 - Filters: `userId = X OR organizationId IN [Y, Z]`
 #### Server-Side Search
 `POST /api/search`
 Perform server-side search (optional, for server-rendered results).
 **Request Body:**
 ```json
 {
  "q": "search query",
  "filters": {
    "documentType": "owner-manual",

    {
      "id": "page-uuid",
      "pageNumber": 1,
      "ocrConfidence": 0.95,
      "ocrLanguage": "en",
      "ocrCompletedAt": timestamp,
      "searchIndexedAt": timestamp
    }
  ],
  "entity": {
    "id": "uuid",
    "name": "My Boat",
    "entityType": "boat"
  },
  "component": {
    "id": "uuid",
    "name": "Main Engine",
    "manufacturer": "Caterpillar",
    "modelNumber": "C7.1"
  }
 }
 ```
 **Status Codes:**
 - `200`: OK
 - `400`: Bad Request - Invalid document ID
 - `401`: Unauthorized
 - `403`: Forbidden - No access to document
 - `404`: Not Found
 **Security:**
 - Ownership verification
 - Organization membership check
 - Document share permissions
 #### List Documents
 `GET /api/documents`
 List documents with filtering.
 **Query Parameters:**
 - `organizationId`: Filter by organization
 - `entityId`: Filter by entity
 - `documentType`: Filter by document type
 - `status`: Filter by status
 - `limit`: Results per page (default: 50)
 - `offset`: Pagination offset (default: 0)
 **Response:**
 ```json
 {
  "documents": [
    {
      "id": "uuid",
      "organizationId": "uuid",
      "entityId": "uuid",
      "title": "Owner Manual",
      "documentType": "owner-manual",
      "fileName": "manual.pdf",
      "fileSize": 1024000,

      "status": "indexed",
      "createdAt": timestamp,
      "updatedAt": timestamp
    }
  ],
  "pagination": {
    "total": 150,
    "limit": 50,
    "offset": 0,
    "hasMore": true
  }
 }
 ```
 #### Delete Document
 `DELETE /api/documents/:id`
 Soft delete a document (marks as deleted).
 **Response:**
 ```json
 {
  "message": "Document deleted successfully",
  "documentId": "uuid"
 }
 ```
 **Status Codes:**
 - `200`: OK
 - `401`: Unauthorized
 - `403`: Forbidden - No permission to delete
 - `404`: Not Found
 **Permissions:**
 - Document uploader
 - Organization admin
 - Organization manager
 ---
 ## Authentication
 All routes require authentication via JWT token (except health checks).
 **Header:**
 ```
 Authorization: Bearer <jwt-token>
 ```
 The authentication middleware attaches `req.user` with:
 ```javascript
 {
  id: "user-uuid",
  email: "user@example.com",
  name: "User Name"
 }
 ```
 ---
 ## Error Handling
 All routes follow consistent error response format:
 ```json
 {
  "error": "Error message",
  "message": "Detailed error description"
 }
 ```
 **Common Status Codes:**
 - `400`: Bad Request - Invalid input
 - `401`: Unauthorized - Missing or invalid authentication
 - `403`: Forbidden - Insufficient permissions
 - `404`: Not Found - Resource not found
 - `500`: Internal Server Error - Server error
 ---
 ## Database Schema
 Routes use the database schema defined in `/server/db/schema.sql`:
 **Tables:**
 - `documents` - Document metadata
 - `document_pages` - OCR results per page
 - `ocr_jobs` - Background job queue
 - `users` - User accounts
 - `organizations` - Organizations
 - `user_organizations` - Membership
 - `entities` - Boats, marinas, condos
 - `components` - Engines, panels, appliances
 - `document_shares` - Sharing permissions
 ---
 ## Dependencies
 **Services:**
 - `db/db.js` - SQLite database connection
 - `services/file-safety.js` - File validation
 - `services/queue.js` - BullMQ job queue
 - `config/meilisearch.js` - Meilisearch client
 **External:**
 - Meilisearch - Search engine (port 7700)
 - Redis - Job queue backend (port 6379)
 - SQLite - Database storage
 ---
 ## Testing
 ### Upload Example
 ```bash
 curl -X POST http://localhost:3001/api/upload \
  -H "Authorization: Bearer <token>" \
  -F "file=@manual.pdf" \
  -F "title=Owner Manual" \
  -F "documentType=owner-manual" \
  -F "organizationId=<uuid>"
 ```
 ### Get Job Status
 ```bash
 curl http://localhost:3001/api/jobs/<job-id> \
  -H "Authorization: Bearer <token>"
 ```
 ### Generate Search Token
 ```bash
 curl -X POST http://localhost:3001/api/search/token \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{"expiresIn": 3600}'
 ```
 ### Get Document
 ```bash
 curl http://localhost:3001/api/documents/<doc-id> \
  -H "Authorization: Bearer <token>"
 ```
 ---
 ## Security Considerations
 1. **File Validation**
   - Extension check (.pdf only)
   - MIME type verification (magic numbers)
   - File size limits (50MB default)
   - Filename sanitization
 2. **Access Control**
   - JWT authentication required
   - Organization-based permissions
   - Row-level security in Meilisearch
   - Document sharing permissions
 3. **Input Sanitization**
   - UUID format validation
   - SQL injection prevention (prepared statements)
   - XSS prevention (no user input in HTML)
 4. **Rate Limiting**
   - 100 requests per 15 minutes per IP
   - Configurable via environment variables
 ---

 # NaviDocs Services
 This directory contains core business logic services for NaviDocs.
 ## Services
 ### OCR Service (`ocr.js`)
 Handles text extraction from PDF documents using Tesseract.js OCR.
 **Key Functions:**
 ```javascript
 import { extractTextFromPDF, extractTextFromImage, checkPDFTools } from './ocr.js';
 // Extract text from PDF (all pages)
 const results = await extractTextFromPDF('/path/to/document.pdf', {
  language: 'eng',
  onProgress: (pageNum, total) => {
    console.log(`Processing page ${pageNum}/${total}`);
  }
 });
 // Result format:
 // [
 //   { pageNumber: 1, text: "Page content...", confidence: 0.94 },
 //   { pageNumber: 2, text: "More content...", confidence: 0.89 },
 //   ...
 // ]
 // Extract from single image
 const result = await extractTextFromImage('/path/to/image.png', 'eng');
 // Check available PDF tools
 const tools = checkPDFTools();
 // { pdftoppm: true, imagemagick: true }
 ```
 **Requirements:**
 - Tesseract.js (installed via npm)
 - PDF conversion tool: `poppler-utils` (pdftoppm) or `imagemagick`
 **Features:**
 - Converts PDF pages to high-quality images (300 DPI)
 - Runs Tesseract OCR on each page
 - Returns confidence scores for quality assessment
 - Graceful error handling per page
 - Progress callbacks for long documents
 ---
 ### Search Service (`search.js`)
 Manages document indexing and search using Meilisearch.
 **Key Functions:**
 ```javascript
 import {
  indexDocumentPage,
  bulkIndexPages,
  removePageFromIndex,
  searchPages
 } from './search.js';
 // Index a single page
 await indexDocumentPage({
  pageId: 'page_doc123_1',
  documentId: 'doc123',
  pageNumber: 1,
  text: 'Extracted OCR text...',
  confidence: 0.94
 });
 // Bulk index multiple pages
 await bulkIndexPages([
  { pageId: '...', documentId: '...', pageNumber: 1, text: '...', confidence: 0.94 },
  { pageId: '...', documentId: '...', pageNumber: 2, text: '...', confidence: 0.91 }
 ]);
 // Search with filters
 const results = await searchPages('bilge pump maintenance', {
  filter: `userId = "user123" AND vertical = "boating"`,
  limit: 20,
  offset: 0
 });
 // Remove page from index
 await removePageFromIndex('doc123', 5);
 ```
 **Features:**
 - Full metadata enrichment from database
 - Multi-vertical support (boat, marina, property)
 - Automatic entity/component linking
 - Tenant isolation via filters
 - Real-time indexing
 **Document Structure:**
 See `docs/architecture/meilisearch-config.json` for complete schema.
 Key fields:
 - `id`: Unique page identifier (`page_{docId}_p{pageNum}`)
 - `vertical`: boating | marina | property
 - `organizationId`, `entityId`, `userId`: Access control
 - `text`: Full OCR text content
 - `systems`, `categories`, `tags`: Metadata arrays
 - Boat-specific: `boatMake`, `boatModel`, `boatYear`, `vesselType`
 - OCR metadata: `ocrConfidence`, `language`
 ---
 ## Usage Examples
 ### Complete Document Upload Flow
 ```javascript
 import { v4 as uuidv4 } from 'uuid';
 import { Queue } from 'bullmq';
 // 1. Upload file and create document record
 const documentId = uuidv4();
 const filePath = '/uploads/boat-manual.pdf';
 db.prepare(`
  INSERT INTO documents (
    id, organization_id, entity_id, uploaded_by,
    title, document_type, file_path, file_name,
    file_size, file_hash, page_count, status, created_at, updated_at
  ) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, 'processing', ?, ?)
 `).run(
  documentId,
  orgId,
  boatId,
  userId,
  'Prestige F4.9 Owner Manual',
  'owner-manual',
  filePath,
  'boat-manual.pdf',
  fileSize,
  fileHash,
  pageCount,
  Date.now() / 1000,
  Date.now() / 1000
 );
 // 2. Create OCR job
 const jobId = uuidv4();
 db.prepare(`
  INSERT INTO ocr_jobs (id, document_id, status, created_at)
  VALUES (?, ?, 'pending', ?)
 `).run(jobId, documentId, Date.now() / 1000);
 // 3. Queue background processing
 const ocrQueue = new Queue('ocr-jobs', {
  connection: { host: 'localhost', port: 6379 }
 });
 await ocrQueue.add('process-document', {
  documentId: documentId,
  jobId: jobId,
  filePath: filePath
 });
 console.log(`Document ${documentId} queued for OCR processing`);
 ```
 ### Search Integration
 ```javascript
 // User searches for maintenance procedures
 const query = 'blackwater pump maintenance';
 const results = await searchPages(query, {
  // Only show user's documents
  filter: `userId = "${userId}"`,
  limit: 10
 });
 // Results include:
 results.hits.forEach(hit => {
  console.log(`
    Document: ${hit.title}
    Page: ${hit.pageNumber}
    Boat: ${hit.boatName} (${hit.boatMake} ${hit.boatModel})
    Confidence: ${(hit.ocrConfidence * 100).toFixed(0)}%
    Snippet: ${hit._formatted.text.substring(0, 200)}...
  `);
 });
 ```
 ### Monitoring OCR Progress
 ```javascript
 // Poll job status
 const jobStatus = db.prepare(`
  SELECT status, progress, error FROM ocr_jobs WHERE id = ?
 `).get(jobId);
 console.log(`Status: ${jobStatus.status}`);
 console.log(`Progress: ${jobStatus.progress}%`);
 if (jobStatus.status === 'failed') {
  console.error(`Error: ${jobStatus.error}`);
 }
 // Or use BullMQ events
 const job = await ocrQueue.getJob(jobId);
 job.on('progress', (progress) => {
  console.log(`Processing: ${progress}%`);
 });
 ```
 ---
 ## Error Handling
 All services use consistent error handling:
 ```javascript
 try {
  await indexDocumentPage(pageData);
 } catch (error) {
  if (error.message.includes('Document not found')) {
    // Handle missing document
  } else if (error.message.includes('Meilisearch')) {
    // Handle search service errors
  } else {
    // Generic error handling
  }
 }
 ```
 **Common Errors:**
 - `OCR extraction failed`: PDF conversion tools missing or file corrupted
 - `Failed to index page`: Meilisearch unavailable or configuration issue
 - `Document not found`: Database record missing
 - `Search failed`: Invalid query or filters
 ---
 ## Performance Considerations
 ### OCR Service
 - **Speed**: ~3-6 seconds per page (depends on content density)
 - **Quality**: 300 DPI provides optimal OCR accuracy
 - **Memory**: ~50-100 MB per worker process
 - **Temp Files**: Cleaned up automatically after processing
 **Optimization:**
 ```javascript
 // Process multiple documents in parallel (in worker)
 OCR_CONCURRENCY=2  // Process 2 docs at once
 ```
 ### Search Service
 - **Indexing**: ~10-50ms per page
 - **Search**: <50ms for typical queries
 - **Index Size**: ~1-2 KB per page
 **Best Practices:**
 - Use filters for tenant isolation
 - Limit results with pagination
 - Bulk index when possible
 - Use specific search terms
 ---
 ## Testing
 Run the test suite:
 ```bash
 # Test OCR pipeline
 node scripts/test-ocr.js
 # Test individual service
 node -e "
  import('./services/ocr.js').then(async (ocr) => {
    const tools = ocr.checkPDFTools();
    console.log('Available tools:', tools);
  });
 "
 ```
 ---
 ## Configuration
 Environment variables:
 ```bash
 # Meilisearch
 MEILISEARCH_HOST=http://localhost:7700
 MEILISEARCH_MASTER_KEY=masterKey
 MEILISEARCH_INDEX_NAME=navidocs-pages
 # Database
 DATABASE_PATH=/data/navidocs.db
 # Redis (for BullMQ)
 REDIS_HOST=localhost
 REDIS_PORT=6379
 ```
 ---
 ## Development
 ### Adding New Search Filters
 Edit `search.js` and add to `buildSearchDocument()`:
 ```javascript
 // Add custom metadata field
 if (metadata.customField) {
  searchDoc.customField = metadata.customField;
 }
 ```
 Update Meilisearch config in `docs/architecture/meilisearch-config.json`:
 ```json
 {
  "settings": {
    "filterableAttributes": [
      "customField"  // Add here
    ]
  }
 }
 ```
 ### Supporting New Languages
 ```javascript
 // Install Tesseract language data
 sudo apt-get install tesseract-ocr-fra  // French
 sudo apt-get install tesseract-ocr-spa  // Spanish
 // Use in OCR
 const results = await extractTextFromPDF(pdfPath, {
  language: 'fra'  // or 'spa', 'deu', etc.
 });
 ```

 # NaviDocs OCR Pipeline
 ## Overview
 The OCR pipeline processes PDF documents in the background, extracting text from each page and indexing it in Meilisearch for fast, searchable access.
 ## Architecture
 ```
 Upload PDF → Create OCR Job → BullMQ Queue → OCR Worker → Database + Meilisearch
 ```
 ### Components
 1. **OCR Service** (`services/ocr.js`)
   - Converts PDF pages to images using external tools (pdftoppm or ImageMagick)
   - Runs Tesseract.js OCR on each image
   - Returns structured data with text and confidence scores
 2. **Search Service** (`services/search.js`)
   - Indexes document pages in Meilisearch
   - Builds proper document structure with metadata
   - Supports multi-vertical indexing (boat, marina, property)
 3. **OCR Worker** (`workers/ocr-worker.js`)
   - BullMQ background worker processing jobs from 'ocr-jobs' queue
   - Updates job progress in real-time (0-100%)
   - Saves OCR results to `document_pages` table
   - Indexes pages in Meilisearch with full metadata
   - Updates document status to 'indexed' when complete
 ## Setup
 ### 1. Install System Dependencies
 The OCR pipeline requires PDF to image conversion tools:
 ```bash
 # Ubuntu/Debian
 sudo apt-get update
 sudo apt-get install -y poppler-utils imagemagick tesseract-ocr
 # macOS
 brew install poppler imagemagick tesseract
 # Verify installation
 which pdftoppm
 which convert
 which tesseract
 ```
 ### 2. Install Node Dependencies
 ```bash
 cd server
 npm install
 ```
 ### 3. Start Redis
 BullMQ requires Redis for job queue management:
 ```bash
 # Using Docker
 docker run -d -p 6379:6379 redis:alpine
 # Or install locally
 sudo apt-get install redis-server
 redis-server
 ```
 ### 4. Start Meilisearch
 ```bash
 # Using Docker
 docker run -d -p 7700:7700 \
  -e MEILI_MASTER_KEY=masterKey \
  -v $(pwd)/data.ms:/data.ms \
  getmeili/meilisearch:latest
 # Or download binary
 curl -L https://install.meilisearch.com | sh
 ./meilisearch --master-key=masterKey
 ```
 ### 5. Start the OCR Worker
 ```bash
 # Run worker directly
 node workers/ocr-worker.js
 # Or use process manager
 pm2 start workers/ocr-worker.js --name ocr-worker
 ```
 ## Usage
 ### Creating an OCR Job
 ```javascript
 import { Queue } from 'bullmq';
 import { v4 as uuidv4 } from 'uuid';
 const ocrQueue = new Queue('ocr-jobs', {
  connection: { host: '127.0.0.1', port: 6379 }
 });
 // Create job in database
 const jobId = uuidv4();
 db.prepare(`
  INSERT INTO ocr_jobs (id, document_id, status, created_at)
  VALUES (?, ?, 'pending', ?)
 `).run(jobId, documentId, Date.now() / 1000);
 // Add job to queue
 await ocrQueue.add('process-document', {
  documentId: documentId,
  jobId: jobId,
  filePath: '/path/to/document.pdf'
 });
 ```
 ### Monitoring Job Progress
 ```javascript
 // Get job from queue
 const job = await ocrQueue.getJob(jobId);
 // Check progress
 const progress = await job.progress(); // 0-100
 // Check database for status
 const jobStatus = db.prepare(`
  SELECT status, progress, error FROM ocr_jobs WHERE id = ?
 `).get(jobId);
 ```
 ### Searching Indexed Pages
 ```javascript
 import { searchPages } from './services/search.js';
 // Search all pages
 const results = await searchPages('bilge pump maintenance', {
  limit: 20,
  offset: 0
 });
 // Search with filters (user-specific)
 const results = await searchPages('electrical system', {
  filter: `userId = "${userId}" AND vertical = "boating"`,
  limit: 10
 });
 // Search with organization access
 const results = await searchPages('generator', {
  filter: `organizationId IN ["org1", "org2"]`,
  sort: ['pageNumber:asc']
 });
 ```
 ## Database Schema
 ### ocr_jobs Table
 ```sql
 CREATE TABLE ocr_jobs (
  id TEXT PRIMARY KEY,
  document_id TEXT NOT NULL,
  status TEXT DEFAULT 'pending',      -- pending, processing, completed, failed
  progress INTEGER DEFAULT 0,         -- 0-100
  error TEXT,
  started_at INTEGER,
  completed_at INTEGER,
  created_at INTEGER NOT NULL,
  FOREIGN KEY (document_id) REFERENCES documents(id) ON DELETE CASCADE
 );
 ```
 ### document_pages Table
 ```sql
 CREATE TABLE document_pages (
  id TEXT PRIMARY KEY,
  document_id TEXT NOT NULL,
  page_number INTEGER NOT NULL,
  -- OCR data
  ocr_text TEXT,
  ocr_confidence REAL,
  ocr_language TEXT DEFAULT 'en',
  ocr_completed_at INTEGER,
  -- Search indexing
  search_indexed_at INTEGER,
  meilisearch_id TEXT,
  metadata TEXT,                      -- JSON
  created_at INTEGER NOT NULL,
  UNIQUE(document_id, page_number),
  FOREIGN KEY (document_id) REFERENCES documents(id) ON DELETE CASCADE
 );
 ```
 ## Meilisearch Document Structure
 Each indexed page follows this structure:
 ```json
 {
  "id": "page_doc_abc123_p7",
  "vertical": "boating",
  "organizationId": "org_xyz789",
  "organizationName": "Smith Family Boats",
  "entityId": "boat_prestige_f49_001",
  "entityName": "Sea Breeze",
  "entityType": "boat",
  "docId": "doc_abc123",
  "userId": "user_456",
  "documentType": "component-manual",
  "title": "8.7 Blackwater System - Maintenance",
  "pageNumber": 7,
  "text": "The blackwater pump is located...",
  "systems": ["plumbing", "waste-management"],
  "categories": ["maintenance", "troubleshooting"],
  "tags": ["bilge", "pump", "blackwater"],
  "boatName": "Sea Breeze",
  "boatMake": "Prestige",
  "boatModel": "F4.9",
  "boatYear": 2024,
  "language": "en",
  "ocrConfidence": 0.94,
  "createdAt": 1740234567,
  "updatedAt": 1740234567
 }
 ```
 ## Error Handling
 The OCR pipeline handles errors gracefully:
 - **PDF Conversion Errors**: Falls back to alternative tools or returns blank page
 - **OCR Errors**: Stores page with empty text and confidence = 0
 - **Indexing Errors**: Logs error but continues processing other pages
 - **Worker Errors**: Updates job status to 'failed' and stores error message
 ## Performance
 ### Optimization Tips
 1. **Concurrency**: Adjust `OCR_CONCURRENCY` environment variable (default: 2)
 2. **Rate Limiting**: Worker processes max 5 jobs per minute
 3. **Image Quality**: Uses 300 DPI for optimal OCR accuracy
 4. **Cleanup**: Temporary image files are automatically deleted
 ### Benchmarks
 - Small PDF (10 pages): ~30-60 seconds
 - Medium PDF (50 pages): ~2-5 minutes
 - Large PDF (200 pages): ~10-20 minutes
 ## Troubleshooting
 ### PDF Conversion Fails
 ```bash
 # Check if tools are installed
 node -e "import('./services/ocr.js').then(m => console.log(m.checkPDFTools()))"
 # Install missing tools
 sudo apt-get install poppler-utils imagemagick
 ```
 ### Tesseract Language Data Missing
 ```bash
 # Install language data
 sudo apt-get install tesseract-ocr-eng tesseract-ocr-fra
 # For multiple languages
 sudo apt-get install tesseract-ocr-all
 ```
 ### Redis Connection Errors
 ```bash
 # Check Redis status
 redis-cli ping
 # Set Redis host/port
 export REDIS_HOST=localhost
 export REDIS_PORT=6379
 ```
 ### Meilisearch Indexing Fails
 ```bash
 # Check Meilisearch is running
 curl http://localhost:7700/health
 # Set environment variables
 export MEILISEARCH_HOST=http://localhost:7700
 export MEILISEARCH_MASTER_KEY=masterKey
 ```
 ## Development
 ### Running Tests
 ```bash
 # Test OCR service
 node -e "
  import('./services/ocr.js').then(async (ocr) => {
    const results = await ocr.extractTextFromPDF('/path/to/test.pdf');
    console.log(results);
  });
 "
 # Test search service
 node -e "
  import('./services/search.js').then(async (search) => {
    const results = await search.searchPages('test query');
    console.log(results);
  });
 "
 ```
 ### Monitoring Worker
 ```bash
 # View worker logs
 tail -f logs/ocr-worker.log
 # Monitor with PM2
 pm2 logs ocr-worker
 # View queue status
 redis-cli
 > KEYS bull:ocr-jobs:*
 > LLEN bull:ocr-jobs:wait
 ```
 ## Production Deployment
 ### Using PM2
 ```bash
 # Start worker with PM2
 pm2 start workers/ocr-worker.js --name ocr-worker --instances 2
 # Save PM2 config
 pm2 save
 # Auto-start on boot
 pm2 startup
 ```
 ### Using Docker
 ```dockerfile
 FROM node:20-alpine
 # Install system dependencies
 RUN apk add --no-cache \
    poppler-utils \
    imagemagick \
    tesseract-ocr \
    tesseract-ocr-data-eng
 WORKDIR /app
 COPY package*.json ./
 RUN npm ci --production
 COPY . .
 CMD ["node", "workers/ocr-worker.js"]
 ```
 ### Environment Variables
 ```bash
 # Redis
 REDIS_HOST=localhost
 REDIS_PORT=6379
 # Meilisearch
 MEILISEARCH_HOST=http://localhost:7700
 MEILISEARCH_MASTER_KEY=masterKey
