如何在MongoDB中正确使用$ geoIntersects？

Question

I wann to use $geoIntersects for checking whether a point is in a polygon.

I have saved UK regions from here in my mongo database. I saved all geoJSON entity with mongoose-geojson-schema module.

Here is defined schema in mongoose

var geozoneSchema = mongoose.model('Geozone', {
    geoFeature:  GeoJSON.Feature,
    average:    {type: Number, default: null},
    updated_at: {type: Date, default: Date.now}
});

I wrote this query, but it didn't work.

Geozone.findOne({
    "geometry.coordinates": {
        "$geoIntersects": {
            "$geometry": {
                "type": "Point",
                "coordinates": fakeUser.loc
            }
        }
    }
}, function(err, foundGeozone) {
    if (err) throw err;
    console.log('found geozone: ', foundGeozone);
    if (foundGeozone) {
        console.log('found geozone! Good! Save User.');
    }
});

In fakeUser.loc is stored this point

 user.loc = [-3.2, 54.5]; //real loc

So I am sure that point really inside particular stored region, but variable foundGeozone is null.

Maybe, my query is wrong or something else. Could you help me?

From the data schema in https://github.com/glynnbird/ukcountiesgeojson , your location field to search should be " geometry ", not " geometry.coordinates ":

Geozone.findOne({
    "geometry": {
        "$geoIntersects": {
            "$geometry": {
                "type": "Point",
                "coordinates": fakeUser.loc
            }
        }
    }
}, function(err, foundGeozone) {
    if (err) throw err;
    console.log('found geozone: ', foundGeozone);
    if (foundGeozone) {
        console.log('found geozone! Good! Save User.');
    }
});

In Victor's case, the location field should be 'geoFeature.geometry'

Geozone.findOne({ 'geoFeature.geometry':  
    {$geoIntersects:
      {$geometry:{ "type" : "Point",
        "coordinates" : [longitude, latitude] } //fakeUser.loc
      }
    }
})
