Subject Re: Parent child relationship, where children aren't nested but separate (like elasticsearch)
Date Thu, 17 Nov 2016 09:23:14 GMT
You want just the usual join (not the block-join). That's the way it
was before nested documents became supported.

Also, Elasticsearch - as far as I remember - stores the original
document structure (including children) as a special field and then
flattens all the children into parallel fields within parent. Which
causes interesting hidden ranking issues, but that's an issue for a
different day.
