Hi,

I am new to hibernate search. Is there any benchmark available for hibernate search?

Thanks.

It uses Apache Lucene as a search engine, so if you're interested in query performance and index update costs, any benchmark related to Lucene will give you a good idea.
On top of Lucene, related to performance it provides smart IndexReader Pools, index sharding, all known IndexWriter optimizations, clever filter caching, optimized field selectors for stored fields. It basically simplifies the usage of Lucene which otherwise requires quite some coding and much experience; it's also integrated with Hibernate's second level cache, and provides features for horizontal scaling of searches. Compared to a database only, it's definitely faster.
