[jira] [Updated] (LUCENE-8105) ReqOptSumScorer could leverage the setMinCompetitiveScore API

     [ https://issues.apache.org/jira/browse/LUCENE-8105?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Adrien Grand updated LUCENE-8105:
---------------------------------
    Attachment: LUCENE-8105.patch

Here is a patch that implements the idea and also makes this scorer propagate two-phase iteration so that it is faster eg. in the case that the optional clause is a phrase.

> If the minimum competitive score is greater than the maximum score of the required clause, we could turn the iterator into a conjunction.
