What is an hybrid index?

janchorowski|1 year ago

An index that combines multiple indexing techniques, e.g. vector search with more classical information retrieval techniques such as BM25. We found that they have different strengths: vector indexes are very good at getting synonyms and indirect matches, while classical term-based indexes are better for direct queries. Hybridization gives you the best of both worlds.
