我也遇到这个问题，在云函数里面写的聚合查询，限制30公里以内，结果是1000公里以外的都查询出来了
async search(data, uid) {
const cmd = this.db.command;
let {
longitude,
latitude,
type,
} = data;
let result = await this.collection.aggregate()
.geoNear({
distanceField: 'juli', // 输出的每个记录中 distance 即是与给定点的距离
spherical: true,
near: new this.db.Geo.Point(longitude, latitude),
maxDistance: 30000, //限制30km
minDistance: 0,
query: {
isOnline: true,
type: type,
},
key: 'home_address.location', // 若只有 location 一个地理位置索引的字段，则不需填
includeLocs: 'home_address.location', // 若只有 location 一个是地理位置，则不需填
})
.project({
mobile: 0
})
.skip((data.page - 1) * data.limit)
.limit(data.limit)
.end()
return result.data;
}
