title: RegEx to Match Query String on App Engine Console Log
body: <p>I am trying to use labels within the app engine console to search for url pattern:</p>
  
  <pre><code>/path?company_id=1234
  </code></pre>
  
  <p>I am using the label filter:</p>
  
  <pre><code>querystring:/(company_id=1234)
  </code></pre>
  
  <p>I get nothing back even though I can see it in the log, can someone explain what I am doing wrong here? I tried it in a RegEx checker and it works. Thanks! </p>
