Subject [jira] [Commented] (SOLR-6700) ChildDocTransformer doesn't return correct children after updating and optimising solr index
Date Wed, 01 Apr 2015 21:21:54 GMT

    [ https://issues.apache.org/jira/browse/SOLR-6700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14391487#comment-14391487
] 

Shawn Heisey commented on SOLR-6700:
------------------------------------

Releases in the major version prior to what's current are done on an as-needed basis.  If
there's no compelling reason for a new release (something that causes problems for a large
number of users), there won't be one.  You can always check out the lucene_solr_4_10 branch
and build it yourself.

> As can be seen, the document with id:2 now contains the child with id:11 that belongs
to the document with id:1. 
> I haven't found any references on the web about this except http://blog.griddynamics.com/2013/09/solr-block-join-support.html
> Similar issue: SOLR-6096
> Is this problem known? Is there a workaround for this?
