title: fetching an object from db using the "offset" parameter chrage too many SMALL OPERATIONS
body: <p>Im getting objects from google app engine db using the offset parameter:</p>
  
  <pre><code>MyModel.all(keys_only=True).filter("level =", level).filter("state &gt;=", state).fetch(limit, offset)
  </code></pre>
  
  <p>when im looking at the app stats im seing that the charged SMALL OPERATIONS is increasing in direct relation with the offset value.</p>
  
  <p>is it possible? im expecting to be able to fetch objects from a certain point and pay only for the fetched data, I think im doing something wrong here, any suggestions?</p>
