[jira] [Commented] (LUCENE-6145) Make
EarlyTerminatingSortingCollector smarter about when it can early terminate
[ https://issues.apache.org/jira/browse/LUCENE-6145?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14261235#comment-14261235 ]
Robert Muir commented on LUCENE-6145:
-------------------------------------
I am +1 to the patch, but not excited about permanently requiring the user to pass a MergePolicy to this collector.
One reason is that it makes it harder to integrate with other search code. E.G. somewhere i made a patch to allow inexact results/hit counts as flags to indexsearcher, which would make this collector much easier to use (and also allow other tricks).
But this means somehow we have to serialize the "sort" better, which is complicated. So +1 to the patch for now :)

> Today EarlyTerminatingSortingCollector only early-terminates if the sort order matches exactly the index-time sort order. It should also early-terminate when the sort order is a prefix of the index-time sort order.
