Check out booleanfilter in contrib/queries. It can be wrapped in a constantScoreQuery

I would like to disable all of Lucene's scoring mechanisms and just run a true Boolean query that returns exactly the documents that match a query specified in Boolean syntax (OR, AND, NOT). No scoring or sorting required. As far as I can see, this is not supported out of the box. Which classes would I have to modify? Would it be enough to create a subclass of Similarity and to ignore all terms but one (coord, say) and make this term return 1 if the query matches the document and 0 otherwise?
