Hi Mike,

unfortunately, you were right about only getting the last child's 
grandchildren. Furthermore, the groups have wrong groupValues: They are 
the document id of the previous parent, not the child. I have opened an 
issue:

https://issues.apache.org/jira/browse/LUCENE-4076

I also created the issue for the missing access to the computed scores:

https://issues.apache.org/jira/browse/LUCENE-4077

Regards,
Christoph
