• Need to find specific quotes, passages, or information
• Navigating to specific pages or chapters in a document
• Researching topics across digital books
• Extracting text for further processing

How It Works

1. First access: Extracts and caches the book content
2. Subsequent access: Uses cached version (invalidates on file change)
3. Search: BM25 algorithm ranks results by relevance
4. Results: Include chapter/page location for reference
