Hybrid Search Explained: Combining Lexical and Semantic Retrieval

By PulseAugur Editorial · [1 sources] ·

This article discusses the implementation of hybrid search, which combines both exact (lexical) and semantic (dense) retrieval methods. It emphasizes the importance of understanding the distinct contributions and failures of each retrieval method before attempting to fuse their results. The author uses a tutorial by Stefan Webb on Milvus 2.5 to demonstrate how to set up a hybrid search system, highlighting the need for clear ownership of dense embeddings and BM25 representations within the schema.
