2.2 GA (v2.2.5)

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 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 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 fields with different indexing strategies.

Enhancements

• Add support for redis COPY command (#2337)
• Add LOAD * for FT.AGGREGATE (#2243)
• Add multi value recursive decent tag (#2207)

Bug fixes

2.2-RC1

This is the first release candidate for RediSearch 2.2

Highlights

This release adds the following main feature:
Indexing, querying and full-text search of JSON documents

Until now, RediSearch has been providing indexing and search capabilities on hashes.
Going forward, by exposing its capabilities to other modules, RedisJSON gives RedisSearch the possibility to index JSON documents.

Another feature part of this release is the ability to profile queries (FT.PROFILE).
This feature will increase the developer experience by empowering them to understand the query execution of RediSearch queries and allow them to optimise them.

Lean more by reading the blog post: Indexing, querying and full-text search of JSON documents with Redis

Getting started:

The easiest way to discover these new features is by using this Docker image. The docker image is publically available and contains Redis together with the main Redis modules, including RediSearch and RedisJSON

docker run -p 6379:6379 redislabs/redismod:preview

For more details read the dedicated page about JSON indexing.

Notes:

• Requires Redis v6 or above
• Requires RediJSON 2.0-RC1 for JSON support
• This is not the GA version of 2.2. The version inside Redis will be 20200 or 2.2.0 in semantic versioning. Since the version of a module in Redis is numeric, we could not add an RC1 flag.
• For production usage, please use RediSearch 2.0.
