I'm trying to get the top (and bottom) N cities, sorted by population and grouped by year.
After some $sorts's, $group's and $push's, I've got something like this:
{_id: "2013",
cities:[

, ...
]},...
Now, I want to do perform {$project: {cities: {$slice: N}}}
I think the $project operator should accept all of the operators the projection document does in the find() command
