I'm trying to get some more information about Parent Child (_parent) mapping functionality in elasticsearch, I have not been able to find a definitive answer to these questions:
Can parent child mappings be nested to more than two levels?
Can a document have multiple parents of different types?
Can a document have multiple children of different types?
It seems like the answer to all these questions is probably "yes" but I don't want to guess, and was hoping to avoid conducting experiments.
