> The parentFilter param to \[child] was once required, and then made only optional if you have a \_nest_path_ field, but I think it can be optional (perhaps obsolete) altogether.  All we have to do is grab the uniqueKey field from the document to be transformed, look this up in the \_root_ field, and you'll get the internal Lucene docId of the first child doc.  No problem, and quick.
