I was using CouchDbRepositorySupport<?> class to manage crud. It seems that querying does not work on this class while create , update, delete do. If you go directly to querying views not via this class then results appear with no problem. Try the tests from the git project that are mentioned in thread (link) below.
I discussed the problem here :
