title: Create a lambda expression for a Query DSL with AND operator in Nest C# (Elastic search)
body: <p>I have a query DSL</p>
  
  <pre><code>{"query":
  {
    "match" : {
      "_all" : {
          "query" : "elastic search document",
          "operator" : "and"
       }
    }
   }
  }
  </code></pre>
  
  <p>Converted it to a lambda expression, but no idea where to give the operator AND in the query.</p>
  
  <pre><code> var queryResult = this.client.Search&lt;dynamic&gt;(d =&gt;
               d.AllIndices()
               .AllTypes().Query(q =&gt; q.Match(m=&gt;m.Query(queryTerm))));
  </code></pre>
