Polishing a great release: Hibernate Search 5.5.3.Final

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.

While the team has been busy implementing great new features such as the Elasticsearch integration for the next 5.6 release, some of you provided interesting feedback on our stable release.

The summary of the feedback I heard is that migrating to the new sorting requirements can be confusing, and there were some issues with our Faceting implementation.

Hibernate Search version 5.5.3.Final is available now, fixing the reported issues and improving the error messages around sorting.

The changelog is rather small, so this time I’ll post it verbatim:

  • HSEARCH-1917 - Cannot index null or empty values for faceted fields

  • HSEARCH-2082 - Documentation refers to @SortField when it should be @SortableField

  • HSEARCH-2085 - Typo in hibernate-search-engine logger

  • HSEARCH-2086 - Long and Date range faceting doesn’t honor hasZeroCountsIncluded

  • HSEARCH-2179 - Hanging during shutdown of SyncWorkProcessor

  • HSEARCH-2193 - LuceneBackendQueueTask does not release the Directory lock on update failures

  • HSEARCH-2200 - Typo in log message

  • HSEARCH-2240 - Parallel service lookup might fail to find the service

  • HSEARCH-2199 - Allows the use of CharFilter in the programmatic API of SearchMapping

  • HSEARCH-2084 - Upgrade to WildFly 10.0.0.Final

  • HSEARCH-2089 - Ensure the performance tests do not use the WildFly embedded version of Search

  • HSEARCH-1951 - Improve resulting error message when applying the wrong Sort Type

  • HSEARCH-2090 - Using the wrong header in the distribution/pom.xml

  • HSEARCH-2241 - Clarify deprecation of setFilter() method on FullTextQuery

Spot inefficient sorting operations easily in test suites

While Hibernate Search already would log a warning when forced to perform a query using a sub-optimal sorting strategy, that wasn’t making it very easy to spot mapping or usage mistakes.

Set this property:

    hibernate.search.index_uninverting_allowed = false

and you’ll have your tests fail with an exception rather than log warnings.

This property is not new in this release, but it’s worth reminding as it makes it much easier to validate your migrations from previous versions.
