> Today a boolean query that is composed of filtering clauses only (more than
> one) cannot skip documents when the search is executed with the TOP_SCORES
> mode. However since all documents have a score of 0 it should be possible to
> early terminate the query as soon as we collected enough top hits. Wrapping
> the resulting boolean scorer in a constant score scorer should allow early
> termination in this case and would speed up the retrieval of top hits case
> considerably if the total hit count is not requested.
