------------------------------------
Summary: MinShouldMatchSumScorer should support approximations
Key: LUCENE-6816
URL: https://issues.apache.org/jira/browse/LUCENE-6816
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Assignee: Adrien Grand
Priority: Minor
This is a tricky yet interesting improvement.
The approximation would return a document as soon as {{min_should_match}} sub
approximations match. Then when matching, it would iterate over approximations
that are on the current document, and if {{matches()}} fails, it would try to
replace the current approximation with one from the tail (approximations that
are behind the current document).
