Redis Search

Single source of guidance for Redis Search — the retrieval surface that spans lexical, numeric, geo, JSON-path, and vector queries. Vector fields are part of the same FT.CREATE machinery as TEXT/TAG/NUMERIC fields, and FT.HYBRID blends lexical and vector ranking in one command, so this skill covers them together.

When to apply

• Creating, modifying, or reviewing a Redis Search index (FT.CREATE, FT.ALTER).
• Writing or optimizing FT.SEARCH, FT.AGGREGATE, or FT.HYBRID queries.
• Picking between TEXT, TAG, NUMERIC, GEO, GEOSHAPE, VECTOR, or JSON-path fields.
• Defining a VECTOR field, choosing HNSW vs FLAT, tuning HNSW parameters.
• Building a retrieval-augmented generation (RAG) pipeline.
• Rolling out a new index schema without downtime.
• Troubleshooting empty results, slow queries, or tokenization issues with FT.EXPLAIN, FT.PROFILE, FT.INFO.

1. Pick the right command

Three query commands. Reach for the narrowest one that fits.
