title: Collection.find is not working properly
body: <p>I am using TingoDB and it uses all Mongodb syntax.
  I have one collection where I am saving around 70K documents but when I run find query without any filter it returns only around 42K documents.
  I do not know what I am doing wrong.</p>
  
  <p>Please find below code,</p>
  
  <pre><code>collection().find().count(function(err, c){
    console.log("count is: ",c);
    console.log("err is: ",err);
  });
  </code></pre>
  
  <p>I also checked the file where records are saved and I am sure not all records are returning.
  Can somebody please help me out here.</p>
  
  <p>TIA
  Mangesh</p>
