Michael McCandless commented on LUCENE-5520:
--------------------------------------------
Unfortunately, we are not allowed to check acceptDocs with parent docIDs: that
bitset is only "valid" for child documents. This is because the primary search
is against children, and IndexSearcher could pass a Filter "down low" as the
acceptDocs.
This also means that your app really must delete all child documents for a
given parent, if you never want to see that parent; but really it's best to
delete parent + all children, whenever you want to delete.
I have an idea for a possible fix ... I'll test and post a patch.
