      To remove a document in a sharded collection, using the justOne option, the shard key is required. This works for the equality operator. Specify a comparison operator and it fails, i.e., $gte, $lt, with the following error:

      WriteResult({
	"nRemoved" : 0,
	"writeError" : {
		"code" : 61,
		"errmsg" : "delete { q: { a: { $gte: 6.0 } }, limit: 1 } does not contain _id or shard key for pattern { a: 1.0 }"
	}
})
