Hi, i'm a student and i'm new in elasticsearch, i would like to develop a java web application that collects the data associated with a specific index  
So we must first develop a connection class to the elastic server using the java API (tansport-client) and then collect the data .  
I searched on google, but i didn't find any tutorial on how to collect the data from specifix index .  
i need help plz.

import java.net.UnknownHostException;

import org.elasticsearch.action.get.GetResponse;  
import org.elasticsearch.client.Client;  
import org.elasticsearch.client.transport.TransportClient;  
import org.elasticsearch.common.settings.Settings;  
import org.elasticsearch.common.transport.InetSocketTransportAddress;

> 
> static Client client = null ;

> public static void main(String args) {  
> // TODO Auto-generated method stub
