title: Show the top n 404 requests in kibana
body: <p>I would like to show the top n requests from an apache access.log, that resulted in a 404 in Kibana. The problem is, that the <code>request</code>-field is splitted into path tokens of the complete request, so for example if <code>./img/flags/us.png</code> would result in a 404 my table would show <code>flags</code> and <code>img</code> and so on. </p>
  
  <p>Is there a way to fix that in Kibana or does ES need a mapping for that?</p>
  
  <p>Thanks!</p>
