Mongoose geo query does not return correct result

Actually, I've been seeing some mistakes on your issue;

1- Index.

 - 2dsphere index if specifying a GeoJSON point - 2d index if specifying a point using legacy coordinates.

Your schema uses a legacy coordinate field. It's not a GeoJSON field. Because a GeoJSON has to be included a coordinate type value like the following;

location: {            'type': { type: String, default: 'Point' },             coordinates: [Number]           } 

If you want to legacy coordinate field you should use 2d index.

2- the order of lat. and lng. Your codes must start with Longitude

IMPORTANTSpecify coordinates in this order: “longitude, latitude.”

On the other hand if you wanna use legacy 2d index you might use the following codes;

{ location : { $near : [ -73.9667, 40.78 ], $maxDistance: 0.10 } }

The above codes hava a $maxDistance parameter that specifies the radius. I think you should check this out. Beacuse you must consider the following line to find 5 meters proximity.

5 meters = (5 / 6371000) radius of the earth

So, I think the following codes work;

Branch.where('location').near({    center: [long, lat],    maxDistance: 5/6371000,    spherical: true}).exec(function (err, branches) {    if (err) {        return res.status(400)            .send({                message: errors.getErrorMessage(err)            });    }    return res.json(branches);});

Or

Branch.find(    { location : { $near : [ -73.9667, 40.78 ], $maxDistance: 5/6371000 }},     function (err, branches) {        if (err) {            return res.status(400)            .send({                message: errors.getErrorMessage(err)            })        }        return res.json(branches);    })  

I hope this helps, good luck!
