title: Named multi_match query
body: <p>I need a hand here. I have a cross_fields multi_match query and I need to use named queries for each field. I can rewrite it into a bool/should match but then I dont know how to reproduce the cross_fields condition. Any idea? Thanks!</p>
  <p>Multimatch query: Relevance OK, but no named queries</p>
  <pre><code>GET test_index/_search
  {
    &quot;query&quot;: {
      &quot;multi_match&quot;: {
        &quot;query&quot;: &quot;example_query&quot;,
        &quot;fields&quot;: [&quot;name&quot;,&quot;lastname&quot;],
        &quot;type&quot;: &quot;cross_fields&quot;
      }
    }
  }
  </code></pre>
  <p>Bool query: Named queries OK but bad relevance</p>
  <pre><code>GET test_index/_search
  {
    &quot;query&quot;: {
      &quot;bool&quot;: {
        &quot;should&quot;: [
          {
            &quot;match&quot;: {
              &quot;name&quot;: {
                &quot;query&quot;: &quot;example query&quot;,
                &quot;_name&quot;: &quot;name_match&quot;
              }
            }
          },
          {
            &quot;match&quot;: {
              &quot;latname&quot;: {
                &quot;query&quot;: &quot;example query&quot;,
                &quot;_name&quot;: &quot;latname_match&quot;
              }
            }
          }
        ]
      }
    }
