Polishing, polishing and more polishing: Hibernate Search 5.5.4.Final is here!

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 are making good progress on our next major release which focuses on Elasticsearch integration but we don’t forget our beloved users of Hibernate Search 5.5.x and here is a new stable release to prove it!

This bugfix release is entirely based on user feedback so keep it coming!

Hibernate Search version 5.5.4.Final is available now and fixes the following issues:

  • HSEARCH-2301 - CriteriaObjectInitializer is suboptimal when we query only one subtype of a hierarchy

  • HSEARCH-2286 - DistanceSortField should support reverse sorting

  • HSEARCH-2306 - Upgrade 5.5.x to Hibernate ORM 5.0.9

  • HSEARCH-2307 - Documentation shouldn’t suggest need for @Indexed of embedded association fields

Small focus on HSEARCH-2301 as it might significantly improve your performances if you index complex hierarchy of objects. Prior to this fix, when querying the database to hydrate the objects, Hibernate Search was using the root type of the hierarchy potentially leading to queries with a lot of joins. Hibernate now builds the most efficient query possible depending on the effective results.

You can see two instances of this issue on Stack Overflow here and here.
