Cannot override search result

[Nguonchhay]

I have override the templateRootPath in the Settings.yaml in my running site:
templateRootPath: 'resource://Reasei.ECommerce/Private/Templates/'
but it does not work.

When I dive into the method initializeView of IndexedSearchController, I see one condition
if ($view instanceof \Neos\Fluid\View\TemplateView) {}
that try to compare with \Neos\Fluid\View\TemplateView. I think it should be \Neos\FluidAdaptor\View\TemplateView
