I am newbie in elastic and I don't understand how should I work with transport client connections. Should I use singleton for Client, something like

class ElasticClientManager {  
private static Client client;

public static Client getClient(){  
if (client==null) {  
Settings settings = ImmutableSettings.settingsBuilder()  
.put("cluster.name", "elasticsearch")  
.put("client.transport.sniff", true).build();

```
   client = new TransportClient(settings)
        .addTransportAddress(new InetSocketTransportAddress("localhost",9300));
}

```

return client;  
}  
}

By other words - I create one client and keep the reference in it in singleton. Every time I need to query elastic I do

Client client = ElasticClientManager.getClient();  
GetResponse getResponse = client.prepareGet(....).execute().actionGet();

Is such approach right?
