title: Evernote, most efficeint way to find notes with tasks
body: <p>I'm building a simple app to list all my todos form Evernote and other apps. To find them form Evernote I am searching for all notes then filter those that contains <code>&lt;en-todo</code>.</p>
  
  <p>But there may be a better way than retreiving all content and filtering ?</p>
