I get NPE when I want to get nbHits, and I cannot get the value of any other field. But, when I disable this line, I get responses without error:  
nbHits += response.getHits().getTotalHits();`

there is my whole code :

```
public static void requestBuilder(ArrayList<String> formulae) {
		
		ArrayList<SearchRequestBuilder> srb = new ArrayList<SearchRequestBuilder>(formulae.size());	
			
		
		Client client = TransportClient.builder().build()
				.addTransportAddress(new InetSocketTransportAddress(new InetSocketAddress("localhost",9300))); 
	
	int i = 0;
		
		MultiSearchRequestBuilder sr = client.prepareMultiSearch();
		for (String formula : formulae) {
			srb.add(client.prepareSearch(index).setSource(formula));
		    sr.add(srb.get(i));
			i += 1;
		} 

		MultiSearchResponse resp = sr.execute().actionGet(); 
	
			long nbHits = 0;
			for (MultiSearchResponse.Item item : resp.getResponses()){
				SearchResponse response = item.getResponse();
			//	nbHits += response.getHits().getTotalHits();
				System.out.println(response);
			}  
		
	client.close(); 
	  		
	}

```

But when I use the following code, I can get get results from any field:

```
SearchResponse response = client.prepareSearch()
				    .setIndices(index)
				    .setSource(formulae.get(1))			
				    .execute()
				    .actionGet();
						
					for (SearchHit hit : response.getHits()) {
						String get = hit.getSource().get("text").toString();
				       	System.out.println(get);
					}

```

How can I do the same with MultiSearch Api?
