Hi Paul, The mapping and query that you're sharing make sense and should work. I verified that with a small recreation: https://gist.github.com/martijnvg/8639841
What I think you're running into is that a document of type 'myParent' doesn't have the field `weight`. Can you check if that is the case? If so you might want to add a `null_value` for the weight field, so that all `myParent` docs have a value for the weight field.
