How do I query the model for geoNear with maxDistance of 1km?
This is my mongoose schema -
var userDestinationSchema = mongoose.Schema({
uid: String,
update_time: Date,
location:{ //<INDEXED as 2d>
lon: Number,
lat: Number
}
});
var userDestinationModel = mongoose.model('userDestinationModel', userDestinationSchema);
I tried doing this and it ain't working.
userDestinationModel.geoNear([parseInt(req.params.lon,10),parseInt(req.params.lat,10)],
{ maxDistance : 1, spherical : true },
function(err, results, stats) {
console.log(results);
});
but when I remove spherical : true
it works.
What is the unit of maxDistance? //Answer: Radian in case of Legacy Coordinate.
DataSample:
{ _id: ObjectId("52f89d8cdbe6f9ea80344fd9"), location: { lon: 165, lat: 165 }, uid: "testuser2", update_time: ISODate("2014-02-10T09:36:12.705Z") }
{ _id: ObjectId("52f89d97dbe6f9ea80344fda"), location: { lon: 166, lat: 166 }, uid: "testuser3", update_time: ISODate("2014-02-10T09:36:23.236Z") }
{ _id: ObjectId("52f8a16edbe6f9ea80344fdb"), location: { lon: 164, lat: 164 }, uid: "testuser4", update_time: ISODate("2014-02-10T09:52:46.464Z") }
{ _id: ObjectId("52f8a173dbe6f9ea80344fdc"), location: { lon: 164, lat: 164 }, uid: "testuser1", update_time: ISODate("2014-02-10T09:52:51.125Z") }
{ _id: ObjectId("52f8a17fdbe6f9ea80344fdd"), location: { lon: 165, lat: 165 }, uid: "testuser7", update_time: ISODate("2014-02-10T09:53:03.365Z") }

The unit is metres, so you might not be getting correct answer.
For km specify 50*1000
And perhaps you need to edit your querying document according to this:

{ near: POINT_COORDINATES.....
