## v2.2.5 (November 2021)

This is the General Availability release of RediSearch 2.2.

### Headlines

#### Searching and indexing JSON documents

This release introduces the ability to [index, query, and full-text search JSON documents](http://redis.io/docs/latest/develop/ai/search-and-query/indexing) using JSONPath queries.

On the schema creation `FT.CREATE`, it is now possible to map a JSONPath query with a field. When a JSON document is indexed, the value extracted by the JSONPath query is indexed in the given field.

 _This features require the module [RedisJSON 2.0](http://www.redisjson.io) to be installed._ 

#### Profiling queries

With 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`.
That way, it is possible to understand which part of the query is taking most of the resources.

#### Field aliasing

With 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.


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.

Notes:
This is the first GA version of 2.2. The version inside Redis will be 2.2.5 in semantic versioning.
_Since the version of a module in Redis is numeric, we could not add a GA flag._
