advancedSpring AI — Core, ChatClient & RAG
What is hybrid search in RAG? How does it combine vector and keyword search?
Vector search finds conceptually similar chunks; keyword (BM25/full-text) search finds exact term matches. Hybrid search combines both scores (commonly via Reciprocal Rank Fusion) for better recall — important when users search using exact terms like error codes or product IDs that pure vector similarity can miss.
