title: Trying regex pattern on greylog search
body: <p>Hej,</p>
  
  <p>I'm trying to query graylog for any message not containing something that would match the regex pattern:</p>
  
  <pre><code>     (\\w+-)*\\d+
  </code></pre>
  
  <p>For example:
  some-article-x-12397</p>
  
  <p>But normal regex seems not to be working for graylog. The help page doesn't give me enough information.
