SQL QueriesSQL query capabilities for data exploration and analytics
  • Vector search can run without an ANN index as an exhaustive scan. That’s useful while prototyping, but build a vector index before relying on low-latency searches over larger tables.
  • Full-text and hybrid text search require an FTS index on the text column you query. If a table has multiple FTS indexes, specify the target column. FTS also supports phrase, boolean, boosted, multi-match, and fuzzy query forms when you need more than plain terms.
  • Multivector search currently uses cosine similarity and accepts either one query vector or a matrix of query vectors; every query vector must match the inner dimension of the multivector column.
  • Set an explicit .limit(...) for production queries. Query builders also support controls such as prefilter/postfilter, distance ranges, row-id inclusion, offset pagination, and Arrow/Pandas/list result materialization.
