Mongoose near(…) query on 2dsphere indexed field not returning valid results

Question

I am unable to query a mongodb database using mongoose\'s qry.where().near() syntax.

I have a Schema with coordinates stored as an array, indexed as

Seems this is a moongoose bug.

Changing the query to use a GeoJSON object instead of a coordinate pair, as such:

qry.where('loc').near({
    center: {
        type: 'Point',
        coordinates: search.loc
    },
    maxDistance: search.distance * 1000
});

results in the following query:

Mongoose: models.find({ loc: { '$near': { 
        '$maxDistance': 1,
        '$geometry': { type: 'Point', coordinates: [ 10, -20 ] } } } 
    }) { fields: undefined }  

The search now succeeds.

The docs explicitly show a query using a coordinate pair:

query.where('loc').near({ center: [10, 10], maxDistance: 5 });

However, it looks like this doesn't work, and the example should be:

query.where('loc').near({ center: { coordinates: [10, 10], type: 'Point' }, maxDistance: 5 });
