AFAIK, $near
takes an array of the two target values, so you can try giving your values in array: -
db.events.find({location:{ $near : [34, 32],$maxDistance:10 / 3963.192}})
Pregunta
I'm trying to fetch records within a specific radius in km/miles.
mongodb 2d index:
db.collection.ensureIndex({locaction:"2d"})
a record in the collection has the indexed key:
"location" : { "longitude" : 34.791592164168, "latitude" : 32.0516908 0405 }
Calling collection's getIndexes() from shell gives me this:
...{
"v" : 1,
"key" : {
"location" : "2d"
},
"ns" : "events.events",
"name" : "location_2d"
}...
despite all the above, trying to fetch records with this command fails:
> db.events.find({location:{ $near :{ longitude:34,latitude:32},$maxDistance:10 / 3963.192}})
anyone can point out what prevent this from working?
