Chris Coutinho	b8010270c1	fix: Add async/await, PDF metadata, and type safety fixes ... This commit addresses multiple issues with async operations, PDF metadata extraction, and type safety in document processing and search. ## Async/Await Fixes - processor.py:259 - Added await for chunker.chunk_text(content) - processor.py:270 - Added await for bm25_service.encode_batch(chunk_texts) - tests/unit/test_document_chunker.py - Converted all 12 test methods to async ## PDF Metadata Enhancement - pymupdf.py:143 - Added file_size metadata extraction - pymupdf.py:145-206 - Refactored to extract text page-by-page - Manually loop through pages instead of using page_chunks=True - Generate page_boundaries metadata for precise page tracking - Works around pymupdf.layout.activate() breaking page_chunks=True - processor.py:32-66 - Added assign_page_numbers() helper function - Assigns page numbers to chunks based on overlap with page boundaries - Handles chunks spanning multiple pages - processor.py:298-300 - Call assign_page_numbers() for PDF files ## Type Safety Fixes - bm25_hybrid.py:184 - Removed int() conversion of doc_id - semantic.py:131 - Removed int() conversion of doc_id - viz_routes.py:275 - Removed int() conversion of doc_id - Added comments documenting that doc_id can be int (notes) or str (file paths) ## Testing - All 18 tests passing (12 unit + 6 integration) - No type errors in modified files - Container logs show successful processing - Vector viz searches working correctly 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-20 02:37:07 +01:00
Chris Coutinho	6fe5596c13	feat: Implement BM25 hybrid search with native Qdrant RRF fusion ... Replace custom keyword/fuzzy search algorithms with industry-standard BM25 sparse vectors, combined with dense semantic vectors using Qdrant's native Reciprocal Rank Fusion (RRF). This consolidates search architecture and improves relevance for both semantic and keyword queries. Key changes: - Add fastembed dependency for BM25 sparse vector generation - Update Qdrant collection schema to support named vectors (dense + sparse) - Create BM25SparseEmbeddingProvider using FastEmbed's Qdrant/bm25 model - Implement BM25HybridSearchAlgorithm with native Qdrant RRF prefetch - Update document processor to generate both dense and sparse embeddings - Simplify nc_semantic_search() tool to use BM25 hybrid only - Remove legacy keyword.py, fuzzy.py, and custom hybrid.py (736 lines) - Update ADR-014 with implementation notes and test results Benefits: - Consolidated architecture (single Qdrant database) - Native database-level RRF fusion (more efficient) - Industry-standard BM25 (replaces brittle custom keyword search) - Better relevance across semantic and keyword queries - Simplified codebase (-285 net lines) Tests: All 125 tests passing (118 unit, 7 integration) Implements ADR-014: Replace Custom Keyword Search with BM25 Hybrid Search 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-16 06:59:44 +01:00
