title: Elastic Search multi match query can't ignore special characters
body: <p>I have a name field value as &quot;abc_name&quot; so when I search &quot;abc_&quot; I am getting proper results but when I search &quot;abc_@#£&amp;-#&amp;&quot; still I am getting same results. I want my query to ignore this special characters that doesn't matches with my query.</p>
  <p>My query has:</p>
  <ul>
  <li>Multi_match</li>
  <li>type as cross_fields</li>
  <li>operator AND</li>
  <li>I am using search_analyzer standard for my Fields</li>
  </ul>
  <p>And I want this structure as it is otherwise it will affect my other Search behaviour</p>
  <pre><code>  &quot;name&quot;: {
           &quot;type&quot;: &quot;text&quot;,
             &quot;fields&quot;: {
             &quot;keyword&quot;: {
                   &quot;type&quot;: &quot;keyword&quot;,
                      &quot;ignore_above&quot;: 256
                       }
                         },
                       &quot;analyzer&quot;: &quot;autocomplete&quot;,
                   &quot;search_analyzer&quot;: &quot;standard&quot;
                              }
  </code></pre>
