Would it ever be feasible to have a parent/child relationship where the child mapping's
_parent field was optional? Last time I tried it, the results weren't pretty.
I have this exactly scenario, where it's possible to have a child document without a matching parent document - we treat them somewhat differently in our product, but they're still valid to us.
To achieve this currently, I'm forced to have a separate document type for the parent/child specific documents and another for everything, resulting in having to index documents twice - one for each of the two types.
Is this possible to achieve in future releases? Thanks
