+### Get raw JSON results
+
+When the target class is not defined or if the response result is a semi-structured data not tied to an object definition, use a raw JSON data representation as the target class. For example, the below snippet uses `ObjectNode` from jackson.
+
+```java
+SearchResponse<ObjectNode> searchResponse = client.search(b -> b.index(index), ObjectNode.class);
+for (int i = 0; i < searchResponse.hits().hits().size(); i++) {
+  System.out.println(searchResponse.hits().hits().get(i).source());
+}
+```
