title: Grafana filter on unindexed ElasticSearch field (zeros) so they aren't shown in Table Panel
body: <p>We have a table that shows warning counts in our services, but we aren't interested in those that are zero.</p>
  
  <p>Because the warning count is a un-indexed number (integer) we can't include it as a filter criteria.  How can these be removed from our dashboard?</p>
