Spring data MongoDB geospatial - mongodb

Question

I need help.
Here my json stored in MongoDB
{
"forecastTime":3,
"infos": [
{
"location": {
"type": "Point",
"coordinates": [ -10, 10 ]
},
"data" : {
"heading": 136,
"wind": [
{
"sail" : "spi",
"speed" : 8.56
},
{
"sail" : "foc",
"speed" : 12.34
}
]
}
},{
"location": {
"type": "Point",
"coordinates": [ -20, 10 ]
},
"data" : {
"heading": 78,
"wind": [
{
"sail" : "spi",
"speed" : 2.23
},
{
"sail" : "foc",
"speed" : 2.34
}
]
}
}
]
}
I'm looking for the query will retrieve the wind's speed for spi sail with forecast 3 (hours) and for the location at -20 & 10.
So, What will the best solution to do this ?
Thanks
I try with this function but I go no result
public GeoResults<Wind> getWinds(float lon, float lat, int forecast) {
Point point = new Point(lon, lat);
NearQuery geoNear = NearQuery.near(point, Metrics.KILOMETERS).maxDistance(0.01);
Query query = new Query(
Criteria.where("forecastTime").is(forecast)
//.and("type").is(type)
);
query.fields()
.include("data.wind")
;
geoNear.query(query);
GeoResults<Wind> data = mongoTemplate.geoNear(geoNear, Wind.class);
return data;
}
Finally, this sample code works
// the query object
Criteria findForecastCriteria = Criteria.where("forecastTime").is(forecast);
// the field object
Criteria findLocationCriteria = Criteria.where("infos").elemMatch(Criteria.where("location.coordinates").is(new double[]{lon, lat}));
BasicQuery query = new BasicQuery(findForecastCriteria.getCriteriaObject(), findLocationCriteria.getCriteriaObject());
query.fields().include("data.wind");
Grib g = mongoTemplate.findOne(query, Grib.class);
result = new ApiResult(
lon
, lat
, g.getData().get(0).getWind().getSpeed()
);
