+# Geo Hash Grid Aggregation
+
+> More info about geo hash grid aggregation is in the [official elasticsearch docs][1]
+
+A multi-bucket aggregation that works on geo_point fields and groups points into buckets
+that represent cells in a grid.
+
+## Simple example
+
+```JSON
+{
+ "aggregations" : {
+ "agg_GrainGeoHashGrid" : {
+ "geohash_grid" : {
+ "field" : "location",
+ "precision" : 3
+ }
+ }
+ }
+}
+```
+
+And now the query via DSL:
+
+```php
+$geoHashGridAggregation = new GeoHashGridAggregation(
+ 'GrainGeoHashGrid',
+ 'location',
+ 3
+);
+
+$search = new Search();
+$search->addAggregation($geoHashGridAggregation);
+
+$queryArray = $search->toArray();
+```
