[jira] Commented: (SOLR-1682) Implement CollapseComponent

["Jasper van Veghel (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-1682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12969246#action_12969246 ] 

Jasper van Veghel commented on SOLR-1682:
-----------------------------------------

Is there any way to retrieve the request the total number of groups, in despite of the (previously noted) performance penalty involved? We'd like to be able to provide complete paging and total counts, but we can't when the total number of documents is say, 200, but the last group is say, 190. That would mean that the last page in a 10-document pager would be empty.
