             Summary: Standard highlighting doesn't work for ToParentBlockJoinQuery
                 Key: LUCENE-5929
                 URL: https://issues.apache.org/jira/browse/LUCENE-5929
             Project: Lucene - Core
          Issue Type: Bug
          Components: modules/highlighter
            Reporter: Julie Tibshirani


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.
