猫鼬查询与$ near $或其他字段

Question

I'm attempting to return documents by doing a query $or on different fields including a $near query with problems.

Schema

locationSchema{
    ...
    beacon: String,
    access_point: String,
    gps: [],
    ...
}

locationSchema.index({ gps: '2dsphere' });

Query

locations.find({
    '$or': [
        {
            gps: {
                '$near': {
                    '$geometry': {
                        type: 'Point',
                        coordinates: [
                            13.1313131,
                            -4.444444
                        ]
                    },
                    '$maxDistance': 50,
                    distanceField: 'distance',
                    spherical: true
                }
            }
        },
        {
            access_point: '88:A6:BB:26:95:11'
        },
        {
            access_point: '88:A6:C6:26:CC:21'
        }
    ]
},
function(err,locations){
    //DosomethingwithfoundLocations
});

If I just do a query with only the $near input, there is one location returned as expected and if I do the query with just the list of access_point 's there is one location returned, but not when both queries are run at the same time.

I'm assuming this is a bug, but is there anyway I can get this type of query working?

Thanks

This is not supported according to the docs. You can read more about it HERE :

$or supports geospatial clauses with the following exception for the near clause (near clause includes $nearSphere and $near). $or cannot contain a near clause with any other clause.

You can, however use geoWithin and pass in the center operator to achieve the same goal. Keep in mind though that geoWithin does not sort the resulting array.
