Multiple near with mongoose - node.js

Question

I have the following "query":
MySchema
.where('address1.loc').near({
center: {
type: 'Point',
coordinates: user.address1.loc
},
maxDistance: 10 * 1000
}).where('address2.loc').near({
center: {
type: 'Point',
coordinates: user.address2.loc
},
maxDistance: 10 * 1000
})
.exec(function(err, objects) {
console.log(err);
console.log(objects);
if(err) return eachCallback(err);
return eachCallback();
});
My schema has two addresses (one pickup- and one handover-address). So I have to use two "nears". But this doesn't seem to be possible:
{ [MongoError: Can't canonicalize query: BadValue Too many geoNear expressions] name: 'MongoError' }
What are my alternatives?
Update:
I talked to some guys from MongoDB. Although my use case for this is valid, this doesn't seem to be possible out-of-the-box. So I'm looking for a "workaround". If you need details about the use case, let me know.
And here is how I defined the location inside my "addresses":
...
loc: {type: [Number], index: '2dsphere'},
...

Answer 1

I had encountered the same issue and error message. But I cannot remember exactly how I could overcome. I hope we can overcome your issue!
If your schema definition like the following, please try to the below solution;
loc : {
'type': { type: String, default: 'Point' },
coordinates: [Number]
}
Could you check address.loc.coordinates stores as number on your collection?
Alternate way
Try to use $geoWithin operator
I think you can change your questioning clauses like the following. You should use $geoWithin and $centerSphere instead of $near and $maxDistance. You've tried to find records that have loc fields in 10.000 meters proximity. $centerSphere indicates radius, it uses legacy coordinate values (only [longitude, latitude]) and it can used with geoJSON field and 2dsphere index. And your $centerSphere definition must be 10/6371 for 10 km. (tutorial).
If you use a second operator with $near operator it occurs a problem on MongoDB side.
You cannot combine the $near operator, which requires a special geospatial index, with a query operator or command that uses a different type of special index. For example you cannot combine $near with the $text query.
var r = 10/6371;
var area1 = { center: address1.loc.coordinates, radius: r, unique: true }
var area2 = { center: address2.loc.coordinates, radius: r, unique: true }
MySchema
.where('address1.loc').
.within()
.circle(area1)
.where('address2.loc').
.within()
.circle(area2)
.exec(function(err, objects) {
console.log(err);
console.log(objects);
if(err) return eachCallback(err);
return eachCallback();
});
Hope this helps..
