What is in Data / RAG

Retrieval and searchOPEN52

The search layer a question actually goes through: hybrid search, reranking, query planning and the plumbing around a corpus. A store that holds the vectors is a vector database; several products are honestly both and are filed in both.

Ordered by attributes answered — the column we hold for most of them. Blank where we hold none.
