I’m sorry if I’m wrong, but I think the answer of the quiz related with maxDepth and depthField is different from the explanation from the video. Or am I misunderstanding things?
depthField determines a field, which contains value of the number of documents matched by the recursive lookup
this is the correct answer from the quiz
I think the correct answer should be:
depthField determines a field in the result document, which specifies the number of recursive lookups needed to reach that document
