For this I have created 2dsphere on location field as specified in the below link
https://docs.mongodb.com/manual/core/2dsphere/
db.collectionName.createIndex( { location : "2dsphere" } )
Help me to understand If I am doing anything wrong.
try changing $near
to $nearSphere
and also add $minDistance: 0
and $maxDistance: yourmaxdistance
next to $geometry
if it still doesnt work...so it will look like
query = {
location: {
$nearSphere: {
$geometry: {
type: "Point" ,
coordinates: [18.55,73.78],
},
$minDistance: 0,
$maxDistance: //your max will go here
}
}
}
If the above does not work try creating the index again and keep a look out for the output...
Here is an example of an index creation that did not work...
