      > db.test.find(
    { $text: { $search: "dog" } },
    { _id: { $meta: "textScore" } }
)
{
  "_id": 2,
  "words": "dog cat",
  "_id": 2
}

      > db.test.find( { $text: { $search: "dog" } }, { _id: { $meta: "textScore" } } ) { "_id" : 2, "words" : "dog cat" , "_id" : 2 }

      When projecting the {$meta: "textScore"} field over _id the resulting documents contain two _id fields which is impossible in javascript as keys in objects must be unique. Something is wrong here.
