title: elasticsearch date range get yesterday
body: <p>I'm looking a way to get the data from "yesterday"
  instead of:</p>
  
  <pre><code>"range" : {
      "price" : {
          "gt" : "2014-11-24",
          "lt" : "2014-11-26"
      }
  }
  </code></pre>
  
  <p>I would like something like:</p>
  
  <pre><code>"range" : {
      "price" : {
          "eq" : "2014-11-25"
      }
  }
  </code></pre>
  
  <p>Does anybody think it could be possible?</p>
  
  <p>I'm thinking of something like:</p>
  
  <pre><code>"range" : {
      "price" : {
          "gt" : "now-2d",
          "lt" : "now"
      }
  }
  </code></pre>
  
  <p>But I would like to get data from <strong>00:00 am</strong> to  <strong>00:00 pm</strong></p>
