------------------------------------
Summary: BooleanQuery with no scoring clauses cannot skip
documents when running TOP_SCORES mode
Key: LUCENE-8935
URL: https://issues.apache.org/jira/browse/LUCENE-8935
Project: Lucene - Core
Issue Type: Improvement
Reporter: Jim Ferenczi
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.
