-----------------------------------------

             Summary: [child] DocTransformer doesn't work unless (request) fl inlcudes '*'
                 Key: SOLR-14678
                 URL: https://issues.apache.org/jira/browse/SOLR-14678
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Chris M. Hostetter


Discovered this while working on SOLR-14383, affects at least 8.6, not sure how far back.
Whatever the problem is, it seems specific to {{[child]}} transformer, doesn't affect things like {{[value]}}

Here's some quick example queries showing the discrepancy in behavior...
