   Pinecone docs explicitly describe hybrid search combining BM25/keyword and dense/sparse vector signals in a single index, with score_by ranking options and fusion via reciprocal rank fusion or text-match filters, matching the story closely. missing for 10: independent hands-on benchmark of fusion ranking quality (community evidence discusses general search quality but not specifically hybrid fusion behavior).

   Chroma~partialclaimed4/10

   Chroma's docs advertise full-text/regex filtering ("$contains", "$regex") that can be combined with metadata filters, and separately list "Sparse vector search - Lexical search (BM25, SPLADE)" as a roadmap/feature item on the homepage, but no documentation describes a single query API that fuses dense and BM25/sparse scores into one ranked result set. missing for 10: explicit fusion-ranking API/query syntax combining dense+sparse scores, hands-on or benchmark evidence that hybrid fusion actually works, and clarity on whether BM25/SPLADE support is shipped vs. planned.

   Pinecone's first-party Inference API explicitly supports reranking results using reranking models hosted on Pinecone's infrastructure, directly matching the story. Missing for 10: independent hands-on benchmarks/community corroboration of reranking quality and no detail on the range/customizability of reranking models offered.

   The evidence pack covers embeddings, full-text/regex search, sparse lexical search (BM25/SPLADE), forking, and MCP/CLI integrations, but nowhere mentions a built-in or first-party-integrated reranking model (e.g., cross-encoder or Cohere rerank) applied to search results.
