15.2. Apache Lucene and Infinispan Query
In order to perform querying on the entire data set stored in the distributed grid, JBoss Data Grid utilizes the capabilities of the Apace Lucene indexing tool, as well as Infinispan Query.
- Apache Lucene is a document indexing tool and search engine. JBoss Data Grid uses Apache Lucene 3.6.
- Infinispan Query is a toolkit based on Hibernate Search that reduces Java objects into a format similar to a document, which is able to be indexed and queried by Apache Lucene.
In JBoss Data Grid, the Query Module indexes keys and values annotated with Infinispan Query indexing annotations, then updates the index based in Apache Lucene accordingly.
Important
The Query Module is currently only available as a Technical Preview for JBoss Data Grid 6.1.
