We don't yet have a query language. However, there is a project out there that adds search to core jboss cache (not pojo cache):
You could however use this with POJO Cache, since it could return the FQN, that you could then pass to POJO Cache.
Thanks for the reply Jason :) I have been considering doing exactly what you suggest i was just not all that sure that it was the best available option :S
Is there any intention to add query functionality to the cache?
