      The draft in SERVER-92213 uses the trick with $group and $push to compute the rank of documents, but we believe it will be better to go with a version that uses $setWindowFields and $rank to compute the same thing, for performance reasons, and so that it doesn't error when given too much data.

       

      You can sort by {key: {$meta: "sortKey"}}
