Hibernate Search now speaking Elasticsearch 5

Posted by    |      

Hibernate Search is a library that integrates Hibernate ORM with Apache Lucene or Elasticsearch by automatically indexing entities, enabling advanced search functionality: full-text, geospatial, aggregations and more. For more information, see Hibernate Search on hibernate.org.

We just published Hibernate Search version 5.8.0.Beta1, which is now compatible with Elasticsearch versions 5.x.

New improved Elasticsearch client

This release now uses the new Elasticsearch REST client, which is expected to be a safe choice in terms of long term maintenance as it’s sponsored and recommended by the Elasticsearch team.

Compared to the driver we used previously, this one uses a state of the art reactive architecture, so we can take advantage of more efficient resource utilization.

Elasticsearch 2.x is still supported

The new driver is backwards compatible, so we’ll still be able to connect to clusters running Elasticsearch 2.x.

This doesn’t need any configuration flag as Hibernate Search can automatically detect the version of Elasticsearch it’s being pointed to.

The features supported by Elasticsearch 5.x and 2.x are however slightly different and you’ll find that some low level mapping features are documented as compatible with only one specific version.

The migration guide will be updated when this minor release will be feature complete.

New Simple Query String supported by the Query builder DSL

The useful capabilities from Lucene’s SimpleQueryParser are now conveniently exposed by our higher level DSL.

We’ll publish a detailed blog about this new feature soon: stay tuned!

If you can’t wait, we won’t prevent you from peeking into the Simple Query String documentation.

Simplified JNDI configuration

If you integrated any external component into Hibernate Search using JNDI, for example a JMS queue or an Infinispan cache, this configuration was simplified.

You will no longer need to set Hibernate Search specific configuration properties such as how to set the InitialContext for JNDI lookups: only configure Hibernate ORM, and Hibernate Search will inherit the same settings.

See also the JNDI configuration in the Hibernate ORM documentation.

How to get these releases

All versions are available on Hibernate Search’s web site.

Ideally use a tool to fetch it from Maven central; these are the coordinates:

<dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-search-orm</artifactId>
   <version>5.8.0.Beta1</version>
</dependency>

To use the experimental Elasticsearch integration you’ll also need:

<dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-search-elasticsearch</artifactId>
   <version>5.8.0.Beta1</version>
</dependency>

Downloads from Sourceforge are available as well.
