> I'm in the process of upgrading http://jirasearch.mikemccandless.com (based
> on 4.10.x in production today!) to Lucene 6.x, but hit this tricky bug.
> When I run the new test case, I hit this:
> {noformat}
> 1) testBQShouldJoinedChild(org.apache.lucene.search.join.TestBlockJoin)
> java.lang.UnsupportedOperationException

> Not sure how to fix it ... it happens because jirasearch runs SHOULD queries
> against the child docs (one child doc per jira comment) and parent docs text
> fields (one child doc per jira issue).
