Questions tagged [redisearch]

For questions about how to use RediSearch, the open-source search tool built on Redis in which the indexes are entirely in memory.

RediSearch is a Redis module that provides querying, secondary indexing, and full-text search for Redis. To use RediSearch, you first declare indexes on your Redis data. You can then use the RediSearch query language to query that data.

RediSearch uses compressed, inverted indexes for fast indexing with a low memory footprint.

RediSearch indexes enhance Redis by providing exact-phrase matching, fuzzy search, and numeric filtering, among many other features.

Filter on IDs with RediSearch

Is there any way to restrict RediSearch results by a list of document IDs, which would be specified in the request? e.g. something like FT.SEARCH cars fast @id:{100,200,300} would return only fast cars having ID 100, 200, or 300.
