Effective Persistence Using ORM With Hibernate
The document outlines the 'Persistence with Hibernate' course offered by Edureka, covering themes such as Java EE, Hibernate, Spring integration, transaction management, and NoSQL databases. The curriculum includes modules on object-relational mapping (ORM), persistence techniques, query languages, and search capabilities with Hibernate and Lucene. Additional support includes live online classes, course recordings, and a verifiable certificate upon completion.

- 19. Slide 19Slide 19Slide19 www.edureka.co/persistence-with-hibernate Search operation is basically carried via IndexSearcher Directory having indexes are passed to IndexSearcher IndexSearcher reads the indexes in the directory with the help of IndexReader Query to search is created using the QueryParser Search performed with IndexSearcher against the query created by QueryParser IndexSeracher returns TopDocs which contains the complete search details Lucene – Search

Slide 20Slide 20Slide20 www.edureka.co/persistence-with-hibernate Even though Lucence provides very efficient search capabilities , suffers with several mismatches with domain object models Hibernate Search built on top of the Lucence search engine to address the short comings of lucence in domain object models Similarly to Hibernate which has been built in top of the SQL databases, Hibernate search built on top of Lucence Hibernate address the short comings of lucence in domain object models with annotations Manages entities when query made to database or as lucence query to index Hibernate Search Search Request
