[jira] [Commented] (SOLR-12243) Edismax missing phrase queries when
phrases contain multiterm synonyms
[ https://issues.apache.org/jira/browse/SOLR-12243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16650777#comment-16650777 ]
Elizabeth Haubert commented on SOLR-12243:
------------------------------------------
After talking to Steve Rowe, there is a new issue LUCENE-8531 to handle the current Span requirement that sloppy queries be inOrder.
Since the core issue with this ticket was that the span clauses prevents pf/pf2/pf3 from being generated entirely, then it seems prudent to back out the lucene change under this ticket, and add a new one to pick up the reordering when there is a patch to LUCENE-8531.
Updated patch pending shortly.
[~alessandro.benedetti], I will include the query expansion test you added, but update it to reflect that the inOrder=false will become inOrder=true. I'm not sure what the right way to coordinate that with the pull request.
