When a JSON document is indexed, the value extracted by the JSONPath query is indexed in the given field.\n\n _This features require the module [RedisJSON 2.0](https://www.redisjson.io) to be installed._ \n\n#### Profiling queries\n\nWith the new `FT.PROFILE` command, it is now possible to profile in detail the execution time of several internal steps involved in the execution of `FT.SEARCH` and `FT.AGGREGATE`.\nThat way, it is possible to understand which part of the query is taking most of the resources.\n\n#### Field aliasing\n\nWith the support of JSON document indexing, it is now possible to map a JSONPath query to an alias. Therefore, it is possible to index the same value in different indexing attributes with different indexing strategies.\n\n> [!NOTE]\n> As of RediSearch v2.2, index `fields` are now known as `attributes` in order to avoid confusion with hash fields. This change impacts the `FT.INFO` command's response, which might break clients. It is advised to upgrade your application to the latest supported Redis clients prior to upgrading to RediSearch 2.2." }, { "id": "details", "title": "Details", "role": "content", "text": "- Enhancements:\n - #[2337](https://github.com/redisearch/redisearch/issues/2337) Add support for Redis COPY command \n - #[2243](https://github.com/redisearch/redisearch/issues/2243) Add `LOAD *` for `FT.AGGREGATE`\n - #[2207](https://github.com/redisearch/redisearch/issues/2207) Add multi value recursive decent tag\n - #[2188](https://github.com/redisearch/redisearch/issues/2188) Add `UNF` flag for `SORTABLE` fields\n - #[2184](https://github.com/redisearch/redisearch/issues/2184) LLAPI getter functions for score, language, and stopwords list\n - #[2133](https://github.com/redisearch/redisearch/issues/2133) JSON array can be stored in a TAG field\n - #[2153](https://github.com/redisearch/redisearch/issues/2153) Improve FT.INFO complexity to O(1) \n - #[2138](https://github.com/redisearch/redisearch/issues/2138) Add `CASESENSITIVE` to `TAG` fields\n - #[2137](https://github.com/redisearch/redisearch/issues/2137) `FT.INFO` has identifier and attribute for fields\n\n- Bug fixes:\n - #[2341](https://github.com/redisearch/redisearch/issues/2341) Fix score field for JSON\n - #[2325](https://github.com/redisearch/redisearch/issues/2325) Fix escaping for tags\n - #[2269](https://github.com/redisearch/redisearch/issues/2269) Remove empty tag values\n - #[2223](https://github.com/redisearch/redisearch/issues/2223) Replace NULL with empty iterator for child of negative iterator\n - #[2215](https://github.com/redisearch/redisearch/issues/2215) Update field limit on tags\n - #[2143](https://github.com/redisearch/redisearch/issues/2143) Partial JSON documents are not indexed\n - #[2109](https://github.com/redisearch/redisearch/issues/2109) Field loaded with 'AS' can't be used by functions\n\nNotes:\nThis is the first GA version of 2.2.
