+    summary: "Major search quality release. Adds HyDE best-of-two for smarter vector retrieval, optional query expansion (local FLAN-T5 or LLM), FTS-only keyword search, and an MCP server for AI agent integration. Fixes vec0 distance metric (cosine instead of L2) and tag filtering (now SQL-level pre-filtering). Includes configurable BM25 shortcut thresholds and FTS5 field-weighted BM25 with truncated paths to avoid IDF collapse."
