Aggregate and filter from one index to another through a third
This will be difficult to answer because it seems you are missing some details. The easy answer is: use nested documents or parent-child relationship. Which one to use in your case depends on a lot of factors. My suggestion is to try them both and test. See how well they perform. The third option is to denormalize your data completely. That's the reason I asked about updates, how frequent they are, how large a Person document is, how large an Archive document is etc. If you are not prepared to answer these questions, then test nested and parent-child and choose one or the other. Good luck!
