Subject [jira] Commented: (SOLR-2272) Join
Date Wed, 08 Dec 2010 14:52:02 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2272?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12969334#action_12969334

Robert Muir commented on SOLR-2272:
-----------------------------------

bq. This was done for a customer, and it's being contributed back now.

But we can contribute this to the right place. Things like queries and queryparsers don't
need to be added to Solr-only.
Its easier to do this up-front, than after the fact. I felt that it was pulling teeth with
the analyzers, etc.
