I didn’t get what you said. In a recursive query, you have to add all attributes and relations you know that exists and you need.
I don’t quite understand your last question if it is related to Recurse or is it another matter.
Questions:
Display where? or how?
Display unrelated entities in a list?
What is the structure of your data? (Only queries don’t help)
“get_all_comments” are the “request answer”?
It’s plausible, but I need to understand its structure and context to be able to help.
