title: elasticsearch ttl force delete old messages
body: <p>Im set TTL as in <a href="http://dev.nuclearrooster.com/2012/05/15/enable-elasticsearch-ttl-for-graylog2-messages/" rel="nofollow">manual</a>, but elasticsearch documentation said that messages older then TTL time will be not affected, how can i force deletion of older messages?</p>
  
  <p>Or maybe exists some method to delete messages older then 30 days?</p>
