title: Interfacing with MongoDB in CodeIgniter
body: <p>Is there function to throw query mongoDB like this <code>$this-&gt;db-&gt;query($query)</code> because I want  to create mongoDB executor in codeigniter so if I type this query like this:</p>
  
  <pre><code>db.users.find({age:33}) 
  </code></pre>
  
  <p>... codeigniter throw that query directly to mongodb server or is there another way? </p>
