I have indexed multiple documents - each of them have 3 fields ( id, tag , text). Is there an easy way to determine the set of tags for a given query without iterating through all the hits? For example if I have 100 documents in my index and my set of tag = {A, B, C}. Query Q on the text field returns 15 docs with tag A , 10 with tag B and none with tag C (total of 25 hits). Is there a way to determine that the set of tags for query Q = {A, B} without iterating through all 25 hits.
Another way is to use a HitCollector to collect all the hits into a Map and then use TermEnum + TermDocs to walk the tags / docs and see what tag the hit comes from. This would be different to walking the Hits/Documents to fetch the tag from the Document. Not sure if this is very efficient though, depends on the Document count.
