Setting mongoose geospatial index range

Question

I am trying to implement a tilemap using mongodb geospatial indexes. I run a server script which includes the following piece of code:

var TileSchema = mongoose.Schema({
    location: [Number],
    tile_type: Number
});

TileSchema.index({location: '2d'}, {min: 500, max: 500});

But no matter what value I set for 'min' and 'max' properties it still throws error when I try to save a Tile which is eg out of 180 longitude. Is this even the correct way to set these properties in mongoose?

The following does not throw any error.

Tile.on('index', function (err) {
    if (err) console.error(err); // error occurred during index creation
})

A debug log where I tried to assign max and min to 500 and -500:

Listening on port 1337...

Mongoose: tiles.find({ location: { '$geoWithin': { '$box': [ [ -288, -64 ], [ -208, 16 ] ] } } }) { fields: undefined }  
{ [MongoError: point not in interval of [ -180, 180 ] :: caused by :: { 0: -194.0, 1: -24.0 }] name: 'MongoError' }

{ [MongoError: point not in interval of [ -180, 180 ] :: caused by :: { 0: -186.0, 1: -24.0 }] name: 'MongoError' }
Mongoose: tiles.find({ location: { '$geoWithin': { '$box': [ [ -272, -64 ], [ -192, 16 ] ] } } }) { fields: undefined }  
{ [MongoError: point not in interval of [ -180, 180 ] :: caused by :: { 0: -186.0, 1: -24.0 }] name: 'MongoError' }

The find queries in the beginning can be ignored I guess, they are just effect of my scrolling on the map in the game client.

这是由于我每次运行该应用程序时不小心重新创建了索引所导致的，因为我没有意识到我必须在执行此操作之前每次都删除它们。
