See https://issues.apache.org/jira/browse/LUCENE-2756 for an example
test case (this sort of thing was reported by users several times)

in this example, the problem is how the queries are executed, the
thing would rewrite against the individual subs, and then call
Query.combine() to form a "super query", and then run this against all
the subs.

but if instead you just run the query against your subs (rewrite()ing
etc locally), and you merge search results... then you shouldn't see
these issues.
