Solr block join child field with expand gets error

I used solr's nested document support to index my documents. I tried to query both parent and children at the same time. My query is q={!parent which="parent_field"} child_field&wt=json&indent=true&expand=true&expand.field=root&expand.q=: However, some times on particular field I receive the following error:

child query must only match non-parent docs, but parent docID=2147483647 matched childScorer=class org.apache.lucene.search.TermScorer

This error seems to randomly happen. What caused this error? Is there an example of how to filter document by both parent and children using solr?

Block join is used to either a. retrieve parent based on child field match, or b. retrieve all child docs for a parent match but not both. Your query looks like you want to fetch parent documents with child field match. However, have you given "condition match for child_field"? I am not able to see it. documentation here
