[jira] [Commented] (SOLR-14996) Facet incorrect counts when FQ
exclusion applied with collapsing
[ https://issues.apache.org/jira/browse/SOLR-14996?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17238774#comment-17238774 ]
Yevhen Tienkaiev commented on SOLR-14996:
-----------------------------------------
This becomes critical, since this error also produce different set of facets depending on what sequence of shards query is executed.
Can someone seriously take a look on this?
