VerifiedHybrid Search combines Dense Retrieval with sparse retrieval (BM25).76% similarUnverifiedMetadata filtering adopts a 'filter first, then retrieve' strategy, making a single vector library logically equivalent to multiple isolated sub-libraries while avoiding the complexity of a routing layer.73% similarUnverifiedThe retriever in Modular RAG can flexibly switch between dense vector retrieval, sparse keyword retrieval (BM25), or hybrid retrieval without reconstructing the entire pipeline.72% similarUnverifiedModern search systems usually combine lexical ranking with other signals rather than replacing BM25, and BM25's reliability on exact matches is still difficult for vector retrieval to fully replace.72% similar
