Beispiel 2 : Suchen von Geschäften in einem rechteckigen Bereich

Die Abfrage gibt alle Speicher zurück, die in den rechteckigen Bereich fallen, der durch diese Koordinaten definiert ist.

db.stores.find(
  {
    location: {
      $geoWithin: {
        $box: [
          [-142.0012, -51.3041],  // Lower left corner
          [123.3403, 70.1272]     // Upper right corner
        ]
      }
    }
  },
  {
    name: 1,
    location: 1
  }
).limit(2)

Die Abfrage gibt alle Speicher zurück, die in den rechteckigen Bereich fallen, der durch diese Koordinaten definiert ist.
