      If there are no histograms:

      Enterprise test> db.foo.aggregate([ { "$sort" : { a : -1 }}, { "$match" : { b: 123  }} ]).explain();
MongoServerError[Location9695100]: All QSNs must have a CE.

      Instead, the error should have been no histogram found for path to allow the user to take action to recover.
