+# Geo Distance Filter
+
+> More info about geo distance filter is in the [official elasticsearch docs][1]
+
+Filters documents that include only hits that exists within a specific distance from a geo point.
+
+## Simple example
+
+```JSON
+{
+ "filtered" : {
+ "query" : {
+ "match_all" : {}
+ },
+ "filter" : {
+ "geo_distance" : {
+ "distance" : "200km",
+ "pin.location" : {
+ "lat" : 40,
+ "lon" : -70
+ }
+ }
+ }
+ }
+}
+```
+
+And now the query via DSL:
+
+```php
+$geoDistanceFilter = new GeoDistanceFilter(
+ 'pin.location',
+ '200km',
+ ['lat' => 40, 'lon' => -70]
+);
+
+$search = new Search();
+$search->addFilter($geoDistanceFilter);
+
+$queryArray = $search->toArray();
+```
