Geo Hash Grid Aggregation

More info about geo hash grid aggregation is in the official elasticsearch docs

A multi-bucket aggregation that works on geo_point fields and groups points into buckets that represent cells in a grid.

Simple example

{
    "aggregations" : {
        "GrainGeoHashGrid" : {
            "geohash_grid" : {
                "field" : "location",
                "precision" : 3
            }
        }
    }
}

And now the query via DSL:

$geoHashGridAggregation = new GeoHashGridAggregation(
    'GrainGeoHashGrid',
    'location',
    3
);

$search = new Search();
$search->addAggregation($geoHashGridAggregation);

$queryArray = $search->toArray();
