Obtaining and using a Lucene IndexReader within the framework 11.3It also gives additional resources to further explore each topicIt does however provide new querying methods that expose the full-text capabilities --- these are not covered by the traditional Hibernate nor the JPA APIs.Similarly, you should be familiar with the JPA mapping annotations, which are equally extended with additional full-text mapping annotations to define which fields you want to be indexed, and with which indexing options.Download Hibernate Search from or use the Maven coordinates: org.hibernate hibernate-search-orm 5.5.5.Final Hibernate Search is available in Maven Central so you typically dont need to enable any specific Maven repository.The version of Hibernate Search to use is not the same as the version of Hibernate ORM which you might already be using, so you need to pick a compatible version.For this guide well use the following combination of versions which are compatible - as you can typically find out yourself by reading either the Maven pom of a release or its README file: Hibernate Search 5.5.5.Final Hibernate ORM (and EntityManager) 5.0.11.Final Apache Lucene 5.3.1 Hibernate Common Annotations 5.0.1.Final Hibernate Search is not released as part of Hibernate ORM, so its version number will often be different --- do not expect them to matchCurrently, he resides in Layton, Utah with wife, Judy and Australian Shepherds, Clancy and Mollystore: allows to store the value in the index, allowing loading over Projection analyze: when disabled, the value will be treated as a single keyword rather than being processed by the Analyzer chain (see Analyzers)
