+### Geo indexing and request
+
+You can make request using geo_distance filter. This can be done using GeoPoint object.
+
+First, here is a sample of an entity with a GeoPoint field
+
+```java
+@Document(indexName = "test-geo-index", type = "geo-class-point-type")
+public class AuthorMarkerEntity {
+
+    @Id
+    private String id;
+    private String name;
+
+    private GeoPoint location;
+
+    private AuthorMarkerEntity(){
+    }
+
+    public AuthorMarkerEntity(String id){
+        this.id = id;
+    }
+
+    public String getId() {
+        return id;
+    }
+
+    public void setId(String id) {
+        this.id = id;
+    }
+
+    public String getName() {
+        return name;
+    }
+
+    public void setName(String name) {
+        this.name = name;
+    }
+
+    public GeoPoint getLocation() {
+        return location;
+    }
+
+    public void setLocation(GeoPoint location) {
+        this.location = location;
+    }
+}
+```

 ### XML Namespace
 
 You can set up repository scanning via xml configuration, which will happily create your repositories.
