```
public static void createIndex() throws IOException 
{
TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
        			        .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

final CreateIndexRequestBuilder createIndexRequestBuilder = client.admin().indices().prepareCreate("test");
final XContentBuilder mappingBuilder = jsonBuilder().startObject().startObject("testing")
        	                .startObject("properties").startObject("Tag").field("type", "nested").endObject().startObject("Address").field("type","nested").endObject()
        	                .endObject().endObject().endObject();
        	       
createIndexRequestBuilder.addMapping("testing", mappingBuilder);
createIndexRequestBuilder.execute().actionGet(); 

```

}  
Above is how I am creating the index and mapping.

and inserting the document as:

```
IndexRequestBuilder indexRequestBuilder = client.prepareIndex("test", "testing", "1");
indexRequestBuilder.setSource(Data);
indexRequestBuilder.execute().actionGet();

```

where Data is a HashMap (String, String).

How do I make sure that Tag and Address are of nested type?  
Is this the correct way to insert the document with nested type fields?
