Are you using something like Hibernate to store entities and run search queries? JBoss Cache, as a 2nd level cache in Hibernate, will ensure that cached objects are up-to-date cluster-wide. But basically, you're looking for Invalidation as a cache mode - so that changes in the cache aren't replicated; instead, stale data is invalidated. Have a look at the JBC user guide on this.
