title: Elasticsearch no result with multi_match
body: <p>I have the following mappings with Elasticsearch 7.10:</p>
  <pre><code>PUT /test

                      &quot;type&quot;: &quot;custom&quot;,
                      &quot;tokenizer&quot;: &quot;standard&quot;,
                      &quot;filter&quot;: [

                          &quot;asciifolding&quot;
                      ]
                  }

              }

  <p>Data:</p>

  <p>Query:</p>
  <pre><code>POST /test/_search

      }
  }
  </code></pre>
  <p>Both &quot;akarki@akarmi.hu&quot; and &quot;lufi&quot; exists in the same document, but no result. Why?</p>
  <p>If the query is only &quot;akarki@akarmi.hu&quot; or &quot;lufi&quot; there is a result.</p>
