Simpan data lokasi di dokumen Mongodb

Perbarui dokumen Anda dan buat koleksi baru

db.location.aggregate([
  { "$addFields": {
    "location": {
      "type": "Point",
      "coordinates": ["$location.loc.lng", "$location.loc.lat"]
    },
    "geocode": "$location.geocode"
  }},
  { "$out": "location" }
])

Kemudian buat indeks di location bidang

db.location.createIndex({ "location": "2d" })
