title: How to findAll in mongoosejs?
body: <p>My code is like that:</p>
  
  <pre><code>SiteModel.find(
      {},
      function(docs) {
          next(null, { data: docs });
      }
  );
  </code></pre>
  
  <p>but it never returns anything... but if I specify something in the {}  then there is one record.  so, how to findall?</p>
