Evernote, most efficeint way to find notes with tasks

Question

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 <en-todo.

But there may be a better way than retreiving all content and filtering ?

Answer 1

Search on "todo:true" to find notes with at least one checkbox checked, or "todo:false" to find notes with at least one checkbox unchecked.

See the "Advanced Content Matching" section of this page from Evernote.
