title: Graylog search contains string
body: <p>I need to search in my data, which is <em>apache2</em> log, I need all requests which URL is like so:</p>
  <pre><code>http://*&amp;ucode=jn04
  </code></pre>
  <p>It starts with <code>http</code> and ends with <code>&amp;ucode=jn04</code></p>
  <p>I tried this query :</p>
  <pre><code>http_referer:&quot;http*&amp;ucode=jn04&quot;
  </code></pre>
  <p>but it doesn't work, and it gives me all URLs which end with the number &quot;4&quot;.</p>
  <p>I'm using Graylog 2.4.6</p>
