That's right. Since each time the ENTER button is pressed, is a new search, we should reset the contents of the model.
Further we should also be able to abort the search, namely swich back to the "normal" model. The question is how. We need some event/button or the like...
Should we connect the signal editingFinished() and the clear button with a funktion that asks if both line edits are empty?

noteModel->clear()
and the "switch back" is done in setCurrentFolder() as soon as the user clicks a folder
