What is hybrid search? A method that combines semantic (vector) search with BM25 keyword search, fusing scores to raise retrieval quality and hit rate in RAG systems.
Pure vector search misses exact terms; pure keyword search misses meaning. A practical guide to combining BM25 and vector search in RAG with RRF and contextual retrieval.
The way to boost RAG accuracy is hybrid search: combining BM25 and vector with RRF and adding a cross-encoder reranker. The numbers, the architecture, and Turkish tips.
