[jira] [Created] (LUCENE-8622) Add a MinimumShouldMatch interval iterator

Alan Woodward created LUCENE-8622:
-------------------------------------

             Summary: Add a MinimumShouldMatch interval iterator
                 Key: LUCENE-8622
                 URL: https://issues.apache.org/jira/browse/LUCENE-8622
             Project: Lucene - Core
          Issue Type: Task
            Reporter: Alan Woodward
            Assignee: Alan Woodward
         Attachments: LUCENE-8622.patch

It would be useful to be able to search for intervals that span some subgroup of a set of iterators, allowing us to build a 'some of ' or 'at least' operator - ie, search for terms that appear near at least 3 of a list of 5 terms.
