For your example, you want to issue a query into the cache for the entire value itself (instead of just a field in the value.) In this case you would issue a query like so: cache.keySet(new EqualsFilter(IdentityExtractor.INSTANCE, object)) and you would get back a set of keys that contain this object. Hi Bansi,
