Our customers are running this query where they have a filter on the parent
objects (givenName, familyName etc) and then request the child objects
({!parent which etc)
q=+(givenName:(+UserSearchControllerUTFN +1180460672*)
familyName:(+UserSearchControllerUTFN +1180460672*)) +{!parent
which="type:userAccount”}hereRealm:Test
We get the following error from Solr/Lucene
java.lang.IllegalStateException: child query must only match non-parent docs,
but parent docID=2147483647 matched childScorer=class

Any thoughts?
A previous email
http://lucene.472066.n3.nabble.com/ToParentBlockJoinQuery-java-td4247115.html
suggested that we might split the query into a query and a filter query
q=+{!parent which="type:userAccount”}hereRealm:Test
fq=+(givenName:(+UserSearchControllerUTFN +1180460672*)
familyName:(+UserSearchControllerUTFN +1180460672*))
Is this the same problem?
