Mongodb - Finding GeoNear within nested JSON objects - json

Question

I need to get the closest place near a certain point using this data structure:
[
{
"data_id": "127",
"actual_data": [
{
"id": "220",
"value": "shaul"
},
{
"id": "221",
"value": "3234324"
},
{
"id": "222",
"value": {
"lngalt": [
13.7572225,
-124.0429047
],
"street_number": null,
"political": null,
"country": null,
}
},
{
"id": "223",
"value": "dqqqf1222fs3d7ddd77#Dcc11cS2112s.com"
},
{
"id": "224",
"value": "123123"
},
{
"id": "225",
"value": "lala1"
},
....
},
{
"data_id": "133",
"actual_data": [
{
"id": "260",
"value": {
"lngalt": [
1.7572225,
32.0429047
],
"street_number": null,
"political": null,
"country": null,
}
},
{
"id": "261",
"value": -122.25
}
],
}
]
I used the following query in order to get what I need:
{
"actual_data": {
"$elemMatch": {
"id": "260",
"value.lngalt": {
"$near": {
"$geometry": {
"type": "Point",
"coordinates": [
-73.9667,
40.78
]
},
"$minDistance": 1000,
"$maxDistance": 5000
}
}
}
}
}
But after queering it, I get "Can't canonicalize query: BadValue geoNear must be top-level expr" (error code: 17287). It's strange since I do get the right results when I query without the $near but with $elemMatch only in order to get the exact object with particular value.
Thanks.
SOLVED!
for future refarance I used $geoWithin instead $near function. So my query looks like :
{
"actual_data": {
"$elemMatch": {
"id": "260",
"value.lnglat": {
"$geoWithin": {
"$centerSphere": [
[
-71.07651880000003,
42.353068
],
0.001
]
}
}
}
}
}
PEACE!
