Hi all,
I am wondering whether it is possible to sort a reverse nested aggregation
by the document count of the joined root / document the nested object
belongs to. The counts of the nested objects and the root document counts
can be off.
I was hoping it is possible to do this in ES and not by double traversing
the array to get the sort order by document count right.
Thanks in advance!
/JZ
