Description

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:

1) testBQShouldJoinedChild(org.apache.lucene.search.join.TestBlockJoin)
java.lang.UnsupportedOperationException
	at __randomizedtesting.SeedInfo.seed([4D5C76211B3E41E1:48F4B8C556F02AB0]:0)

	at org.apache.lucene.search.join.TestBlockJoin.testBQShouldJoinedChild(TestBlockJoin.java:233)

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).
