Redis Search

Redis Search is a

  • A rich query language

  • Full-text search

  • Geospatial queries

  • Aggregations

For searching first you have to create INDEXES

FT.CREATE {index_name} ON JSON SCHEMA {json_path} AS {attribute} {type}

  • <indexName>: The name of the index you are creating.

  • [ON <structure>]: Specifies the data structure to index, which can be HASH (default) or JSON if you're indexing JSON documents with RedisJSON.

  • [PREFIX count <prefix> ...]: Defines one or more key prefixes. Only keys that match the prefix(es) will be indexed.

  • SCHEMA: Followed by one or more field definitions.

  • <field>: The name of the field to index.

  • <type>: The type of the field (TEXT, NUMERIC, GEO, or TAG).

FT.CREATE idx:friends ON JSON PREFIX 1 "friends:character:" SCHEMA $.friends[*] AS friend TAG
FT.SEARCH idx:friends "@friend:{Joey Tribbiani}"
FT.CREATE idx:occupation ON JSON PREFIX 1 "friends:character:" SCHEMA $.occupation AS occupation TEXT
FT.SEARCH idx:occupation "*"

FT.SEARCH idx:occupation "Chef"
FT.INFO idx:occupation
