      db.createCollection( "c" ) db.c.ensureIndex({xid: 1, pos: "2dsphere" }) db.c.find({xid: ObjectId( "5475cdeeb307f5e9b8550e6d" ), pos: { $nearSphere: [ 0, 0 ], $maxDistance: 0.1}}).explain()

      This is evident from performing the query directly on an empty collection that does not contain any documents.

      db.c.find({xid: ObjectId("5475cdeeb307f5e9b8550eaa"), pos: { $nearSphere: [ 0, 0 ], $maxDistance: 1}}).explain()
