Hibernate Search 3.2.0 Beta1

Posted by    |       Hibernate Search

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.

It has been quite some time since the latest Hibernate Search release, but we are happy to announce the first beta release of version 3.2.0 with tons of bug fixes and exciting new features. In fact there are so many new features that we are planning to write a whole series of blog entries covering the following topics:

  • The new API for programmatic configuration of Hibernate Search via org.hibernate.search.cfg.SearchMapping.
  • Ability to rebuild the index in parallel threads using the MassIndexer API. This can be as simple as fullTextSession.createIndexer().startAndWait(), but of course there are plenty of options to fine-tune the behavior.
  • Clustering via JGroups as an alternative to the existing JMS solution. The values for the hibernate.search.worker.backend option are jgroupsSlave and jgroupsMaster in this case.
  • Dynamic boosting via the new @DynamicBoost annotation.

Most of these new features are already documented in the Hibernate Search documentation available in the distribution packages. However, there might be still some gaps in the documentation. If you find any let us know via the Forum or Jira. Smaller new features are:

  • New built-in field bridges for the java.util.Calendar and java.lang.Character
  • Ability to configure Lucene's LockFactory using hibernate.search.<index>.locking_strategy with the values simple, native, single or none.
  • Ability to share IndexWriter instances across transactions. This can be activated via the hibernate.search.<indexname>.exclusive_index_use flag.

Of course we also fixed several bugs of which the following are worth mentioning explicitly:

  • HSEARCH-391 Multi level embedded objects don't get an index update
  • HSEARCH-353 Removing an entity and adding another with same PK (in same TX) will not add second entity to index

For a full changelog see the Jira release notes. Last but not least, Hibernate Search depends now on Hibernate Core 3.5 beta2 and Lucene 2.4.1 and is aligned with JPA 2.0 CR1.

Special thanks to our contributors Sanne Grinovero and Amin Mohammed-Coleman who put a lot of effort into this release.

enjoy!
