title: ElasticSearch: How to query a date field using an hours-range filter
body: <p>Currently, I already know how to filter a days range from a (timestamp) date field. That's an easy one:</p>
  
  <pre><code>"range": {
      "date": {
          "gte": "2015-11-01",
          "lte": "2015-11-30"
      }
  }
  </code></pre>
  
  <p>But how to filter dates when you are interested in ranges based on hours like gte:"8:00:00" and lte:"10:00:00"? Is this possible? </p>
  
  <p>My requirement in other words:
  How to get all the events happening this month (15-11-01/15-11-30) but only between 8:00:00 am and 10:00:00?</p>
