title: Elastic search: How extract total count from elastic multi search query response IMultiSearchResponse
body: <p>I have elastic multi-search query that returns me 3 list of documents.</p>
  
  <p>The response in sense looks like:</p>
  
  <pre><code>{
     "responses": [
        {
           ...
           "hits": {
              "total": 0,
              "max_score": null,
              "hits": []
           }
        },
        {
           ...
           "hits": {
              "total": 0,
              "max_score": null,
              "hits": []
           }
        },
        {
           ...
           "hits": {
              "total": 0,
              "max_score": null,
              "hits": []
           }
        }
     ]
  }
  </code></pre>
