title: Elastalert not alerting
body: <p>I am trying to utilize a simple rule using Elastalert, and it seems to not be functioning properly. My rule is:</p>
  
  <pre><code># Elasticsearch host
  es_host: elasticsearch
  
  # The elasticsearch port
  es_port: 9200
  
  name: dzd_count_zero
  
  type: any
  
  index: logstash-*
  
  filter:
  - term:
      project: "drop_zone_dub"
  - terms:
      name: ["s3_count", "dzd_nas_pcount"]
  
  alert:
  - "email"
  
  email:
  - "myemail@m.com"
  </code></pre>
  
  <p>and when I put debug on i get:</p>
  
  <pre><code>elastalert:Ran dzd_count_zero from 2016-03-02 13:59 UTC to 2016-03-02 17:59 UTC: 16 query hits, 0 matches, 0 alerts sent
  </code></pre>
  
  <p>If the rule is 'any' then any query hits should be alerted on, but as you can see it is not. Any ideas?</p>
