Hybrid search: combining BM25 and vector similarity for better RAG
Hybrid search fuses keyword-based BM25 ranking with dense vector similarity to deliver better retrieval than either method alone, especially for domain-specific corpora where exact terms matter alongside semantic meaning. This article covers the theory, implementation patterns, and tuning strategies for hybrid search in production RAG systems.
