> Because WeightedSpanTermExtractor#extract doesn't check for ToParentBlockJoinQuery, the Highlighter class fails to produce highlights for this type of query.
> At first it may seem like there's no issue, because ToParentBlockJoinQuery only returns parent documents, while the highlighting applies to children. But if a client can directly supply the text from child documents (as elasticsearch does if _source is enabled), then highlighting will unexpectedly fail.
> A test case that triggers the bug is attached. The same issue exists for ToChildBlockJoinQuery.
