      Description

      On the 2014-01-02 nightly:

      > db.x.find({x: {$elemMatch: {y: 12, $or:[{z: 1}, {z: 2}]}}})
      		 
      > db.x.find({x: {$elemMatch: {$or:[{z: 1}, {z: 2}], y: 12}}})
      		 
      error: {
      		 
      	"$err" : "Can't canonicalize query: BadValue unknown operator: $or",
      		 
      	"code" : 17287
      		 
      }

      Both work in 2.4.9. I would expect that either both of these queries would work or both would fail.
