Sorting on _id gives incorrect results

[jimmyjones2]

#1584 allowed _id to be filtered on, but also enabled sorting, but this doesn't appear to give the expected result. I presume if _id was indexed this would work correctly, so sorting should only be enabled in this case?

Definitely broken, the current work around is to index _id. Marking as bug.

Fixed by #2113

I've just tried the latest master and I'm still getting the same behavior. I don't think its actually possible to sort on _id unless it's indexed, I did think about sorting internally on _uid, but this would only order on _id correctly if the type was the same.

Interesting. I'm also on the latest master, don't have _id indexed, and receive no sorting option:

Sorry @spenceralger clearly hadn't cleared my cache!
