Hibernate Search 3.0 available: provides full-text search

Hibernate Search 3.0, which
brings full text search capabilities to Hibernate-based applications,
has been released. With Hibernate Search, developers can easily take
advantage of advanced Google-like search features, unattainable in
relational databases, without the need for extra infrastructure coding.


Hibernate Search integrates transparently with Hibernate, the
object/relational (O/R) mapping and persistence engine, with little to
no configuration (past specifying what entities to index). With
advanced features such as query filter and index sharding, Hibernate
Search can be embedded into user applications.

Key features in Hibernate Search 3.0 include:

• Transparent
  index synchronization: This feature eliminates the need to manually
  update the index on data change. Events generated by Hibernate Core
  will trigger the update transparently for the application.
• Seamless integration with the Hibernate and Java Persistence query
  model:
  Hibernate Search embraces both the Hibernate and Java Persistence
  semantic and APIs. As a result, switching from a Hibernate Query
  Language (HQL) query to a full text query requires minimal changes to
  the application.
• Out-of-the-box asynchronous clustering mode:
  Handles clustered applications, this out of the box mode also handles
  gracefully indexing load peaks, avoiding any contention on the online
  system.
• Product extensibility: Developers can extend Hibernate
  Search with a series of extension points for deep index interaction
  customization that helps edge case applications meet their performance
  and architectural requirements and constraints.
