title: App Engine datastore does not support operator OR
body: <p>I am trying to query the google datastore for something like (with pm --> persistanceManager):</p>
  
  <pre><code>String filters = "(  field == 'value' ||  field == 'anotherValue' )";
  Query query = pm.newQuery(myType.class, filters);
  </code></pre>
  
  <p>When I execute - I am getting back: <strong>App Engine datastore does not support operator  OR</strong>.</p>
  
  <p>What's the best approach in people experience for this kind of queries?</p>
  
  <p>Any help appreciated!</p>
