It seems it might be desirable for Heroku users to have a MongoDB Directory for Lucene:
http://stackoverflow.com/questions/14271617/implementing-a-directory-provider-for-hibernate-search-using-mongodb We're not far off from having a solution by using Guillaume's contribution to Infinispan to a MongoDB enabled CacheStore: we use Infinispan's Lucene Directory implementation, so that it benefit from in-VM caching, and have it persist to a MongoDB backend for the slow and long term. What we should do is to make it trivial to setup: I don't expect the average Heroku user to want to dive into the Infinispan manuals. Any takers? I can help with the Infinispan configuration, and hope Guillaume can as well as author of the CacheStore, but we likely need a Heroku user to try it all out.
