# Changelog

<Update label="March 2026">
Added [Upstash Redis Search](/redis/search/introduction) feature, a new extension for searching Redis data. It works with JSON, Hash, and String data, automatically keeps indexes in sync with Redis writes, and supports full-text search, filtering, aggregations, aliases, highlighting, fuzzy matching, phrase queries, and regex matching.

Redis Search is available through the [@upstash/redis](/redis/sdks/ts/overview) and [upstash-redis](/redis/sdks/py/overview) SDKs. If you already use `node-redis` or `ioredis`, you can use the [`@upstash/search-redis`](/redis/search/adapters/node-redis) and [`@upstash/search-ioredis`](/redis/search/adapters/ioredis) wrappers without switching clients.

New Redis Search commands:
- [`SEARCH.CREATE`](/redis/search/command-reference#searchcreate): Create a search index
- [`SEARCH.DROP`](/redis/search/command-reference#searchdrop): Remove a search index
- [`SEARCH.DESCRIBE`](/redis/search/command-reference#searchdescribe): Return metadata about a search index
- [`SEARCH.WAITINDEXING`](/redis/search/command-reference#searchwaitindexing): Wait until pending index updates are visible to queries
- [`SEARCH.QUERY`](/redis/search/command-reference#searchquery): Search documents with a JSON filter
- [`SEARCH.COUNT`](/redis/search/command-reference#searchcount): Count matching documents without returning them
- [`SEARCH.AGGREGATE`](/redis/search/command-reference#searchaggregate): Compute analytics over matching documents
- [`SEARCH.ALIASADD`](/redis/search/command-reference#searchaliasadd), [`SEARCH.ALIASDEL`](/redis/search/command-reference#searchaliasdel), and [`SEARCH.LISTALIASES`](/redis/search/command-reference#searchlistaliases): Manage search index aliases
