## What it is
RediSearch is a Redis module providing a query and indexing engine with secondary indexing, full-text search, vector similarity search, geospatial queries, and aggregations. Starting with Redis 8, it is integrated into Redis itself and no longer released as a standalone module.

## Use cases
- add full-text search to my redis data
- use redis as a vector database for embeddings
- build secondary indexes over redis hashes and json
- run semantic search for a RAG application
- filter and aggregate redis documents with a query language
- geospatial radius queries over stored locations

## When to choose
- you already run Redis and need search, indexing, or vector similarity without a separate database
- you want low-latency full-text and vector search backed by compressed inverted indexes
- you need document, vector, and geospatial querying in one in-memory store

## When to avoid
- you need a standalone module install - it is now part of Redis 8 and no longer released separately
- you need disk-based or very large-than-memory datasets
- you require a non-Redis database or 32-bit systems (unsupported)

## Facets
