eZ announces the availability of 5.4.5, a maintenance release available for all users of eZ Publish Platform 5.4. In addition to 18 bug fixes, it adds two packages that are part of the upcoming eZ Platform release: Solr as a repository search engine, and a revamped Recommendation engine integration.

Follow the 5.4.x Update Instructions to apply this update to your platforms.

Highlights: New Features

This maintenance release introduces a new eZ Platform package: support for Solr as a Repository search engine. Besides this there are several maintenance issues fixed as listed below both coming from support issues and pull requests from community.

Improved Search engine powered by Solr

 

New in 5.4.5, and part of the upcoming eZ Platform release this fall, is support for running API Search queries on top of Solr instead of SQL based search engine (specifically "Legacy" search/storage engine). As Search is essentially powering all Search and Querying ("fetch") operations in Platform stack (aka 5.x/Symfony stack), this specifically means you can expect much more stable performance from your searches and your system*, and much better possibility to scale out for your search needs using Solr.

 

'* See 5.x Architecture diagram for further information about how persistence load operations are cached by Persistence Cache, and Search queries now are delegated to Solr, meaning database is less affected by system load to mainly deal with content updates.


Further reading: Installation documentation for Solr Search Engine, developer info and source code in our Solr Search Engine Bundle repository, and further resources on Apache Solr.

Package Details

Resolving known issues

Known for both Solr and Recommendation:

  • Exception if Binary files in database has invalid path prefix
    • Make sure ezpublish.yml configuration var_dir is configured properly, and that you specify siteaccess when indexing content for Solr via command line.
  • Exception on unsupported Field Types
    • Make sure to configure all FieldTypes (datatypes) in your installation as NullType
  • Content not immediately available 
    • Solr Bundle: Is on purpose not committing changes on Repository updates, but letting you control this using Solr configuration. Adjust Solr autoSoftCommit (visibility of change to search index) and autoCommit (hard commit, for durability and replication) to balance performance and load on your solr instance against needs you have for NRT.
    • Recommendation service: Content should be available within 5-10 minutes after content has been sent to the service by RecommendationBundle.
