title: Get distinct records values
body: <p>Is there a way to query for objects with not same values on some field? For example I have Records:</p>
  
  <pre><code>{ id : 1, name : "my_name", salary : 1200 }
  { id : 2, name : "my_name", salary : 800 }
  { id : 3, name : "john", salary : 500 }
  </code></pre>
  
  <p>Query : find all with NOT_THE_SAME(name)</p>
  
  <p>I just want records with id 1 and 3 because I specified that I don't want records with same value in field <code>name</code> or 2 and 3, it does not matter in this situation.</p>
