[jira] [Commented] (LUCENE-8422) Add Matches iteration to interval queries

    [ https://issues.apache.org/jira/browse/LUCENE-8422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16961456#comment-16961456 ] 

Mikhail Khludnev commented on LUCENE-8422:
------------------------------------------

Why {{CachingMatchesIterator.getSubMatches(...).new MatchesIterator() \{...}.getQuery()}} introduced here throws UnsupportedOpExc? see [https://github.com/apache/lucene-solr/blob/3af4e6adc6b1ffdc5099ba68227ce0dc6b252644/lucene/queries/src/java/org/apache/lucene/queries/intervals/CachingMatchesIterator.java#L127]

I tried to experiment with highlighting Interval queries, didn't find any particular test for it. Thus, I tweaked {{TestUnifiedHighlighter.testBuddhism()}} for using Intervals.phrase(). Turns out it fails roughly at %50 with this exception. The fix is obvious. Don't we need it fixed? I can.
