Hi,

Gotta a question about a specific plugin behavior I'm looking for. I basically need to replace the entire document with another document within a search plugin in some cases. Is this possible?

Parent/child kinda solves this issue for us, but not really since a document can have multiple parents, and even multiple types of parents.

I suspect its not possible because to pull the same document, all children would have to be on the same shard?

Hey,

there is no such functionality. I think this kind of functionality should be put into a post processing step, that fetches the required documents after checking the results and then return that back to the client.

Do you think about searches where the documents returned have links to other documents and they should be fetched, by a series of "get" requests, like a cascade?
