my $geonear function is not returning the expected array of nearest driver in my collection.

i am running these queries to get the result.

to create indexes for geonear i used:

db.dectar_drivers.createIndex({point:"2dsphere"});

to find the nearest driver i have used:

db.dectar_drivers.aggregate([
{
$geoNear: {
near: { type: "Point", coordinates: [ 22.7323132 ,75.8753951] },
distanceField: "total_mileage",
maxDistance: 200,
includeLocs: "loc",
num: 5,
spherical: true
}
}
])
