Subject [jira] [Commented] (SOLR-5425) PostFilters are executed twice when used with grouping
Date Wed, 20 Nov 2013 13:17:35 GMT

    [ https://issues.apache.org/jira/browse/SOLR-5425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13827622#comment-13827622

Shalin Shekhar Mangar commented on SOLR-5425:
---------------------------------------------

I'm not sure that we can avoid this. The post filters must be executed in each of the two
phases to get correct results. Also see Joel's comment on SOLR-5230 here:

> Have experimented with removal at one stage but always comes in with wrong answers and
it seems for now this is necessary. Makes an expensive PostFilter doubly so, which can be
a problem.
