Hybrid search
Hybrid search combines keyword search, such as BM25, with vector search and merges the results, so a system catches both exact term matches and semantically related content.
Hybrid search sits in the Retrieval & memory part of the Agentik {OS} glossary, which defines the words used to build and run AI agent systems.
Also called hybrid retrieval, fusion retrieval.
