RediSearch
Full-Text search over Redis by RedisLabs
See Full Documentation at https://oss.redislabs.com/redisearch/
Overview
RediSearch implements a search engine on top of Redis, but unlike other Redis search libraries, it does not use internal data structures like Sorted Sets.
Inverted indexes are stored as a special compressed data type that allows for fast indexing and search speed, and low memory footprint.
This also enables more advanced features, like exact phrase matching and numeric filtering for text queries, that are not possible or efficient with traditional Redis search approaches.
