title: elk's elastic search dsl case sensitive
body: <p>I'm doing an Elasticsearch Query DSL query on ELK such as:</p>
  <pre><code>{
    &quot;query&quot;: {
      &quot;wildcard&quot;: {
        &quot;url.path&quot;: {
          &quot;value&quot;: &quot;*download*&quot;,
          &quot;boost&quot;: 1,
          &quot;rewrite&quot;: &quot;constant_score&quot;
        }
      }
    }
  }
  </code></pre>
  <p>but it seems is case sensitive (so show only info with &quot;download&quot;, not &quot;Download&quot; or &quot;DOWNLOAD&quot;).
  i.e. is case sensitive.</p>
  <p>can I disable this? and search case insensitive?</p>
