Got the search form and results screen up and running, however currently has a bug where all interaction stops working (e.g. no focus on up/down/left/right) if you use the 'No results found, go back' button. It appears that the history stack is working because the search keyboard view appears, but the user has to reload the app to restore navigation/focus ability. The video player view Back button uses the same 'parentWidget.back()' method call and works. Still trying to investigate.
