I'm not 100% sure, but I think you could use Lucene's scoring for this. So if you ran your query and received N results, loop through them and check the scoring explanation (which I'm not quite sure how to acquire). This should tell you how many terms out of the query were found. This approach should work fine if all terms have the same frequency throughout the docs. If there is one term which is highly frequent in one of the docs, this might fail.
But again, I'm no Lucene pro. I would love to hear an answer myself from one of the Lucene wiz-es.

Tn to search on a field in Lucene. Is there a way to force the search to return documents that match at least say 5 of the query Terms?
