Hibernate Search integrates Lucene

clipped from www.hibernate.org

Hibernate Search

Hibernate Search brings the power of full text search engines to the persistence domain model and Hibernate experience, through transparent configuration (Hibernate Annotations) and a common API.

Full text search engines like Apache Lucene(tm) allow applications to execute free-text search queries. However, it becomes increasingly more difficult to index a more complex object domain model - keeping the index up to date, dealing with the mismatch between the index structure and the domain model, querying mismatches, and so on.

Hibernate Search abstracts you from these problems by solving:

  • The structural mismatch: Hibernate Search takes care of the object/index translation
  • The duplication mismatch: Hibernate Search manages the index, keeps changes synchronized with your database, and optimizes the index access transparently
  • The API mismatch: Hibernate Search lets you query the index and retrieve managed objects as any regluar Hibernate query would do
