I am sorry by the title. I was hard to describe. I have this collection



  {
"_id" : ObjectId("55cb9c666c522cafdb053a68"),
location: {
type: "Point",
coordinates: [-73.856077, 40.848447]
},
"maxDistancevalue" : 100000
}


Now I want to find of the current location is within: 100000 as defined is the collection by "maxDistancevalue"



The code will be like this. But how set the maxDistancevalue?



  db.places.find(
{
location:
{ $near :
{
$geometry: { type: "Point", coordinates: [ -73.9667, 40.78 ] },
$minDistance: **??????, -->maxDistancevalue**
$maxDistance: 0
}
}
}
)

          You can use Aggregation Framework's $geoNear pipeline stage to reference other existing field. It requires 2dsphere index to be created on your collection, so start with:



          db.places.createIndex({location:"2dsphere"});


          and then you can run your aggregate() query:



          db.places.aggregate([
          {
          $geoNear: {
          near: { type: "Point", coordinates: [ -73.9667, 40.78 ] },
          distanceField: "dist.calculated",
          maxDistance: "$maxDistancevalue"
          }
          }
          ])
