How to create catch-all instead of 404 error page

[hlorofos]

I'm trying to create a catch all page which would work like this

Route::statamic('{q}', 'landing', ['layout' => 'custom_search']);

this is my last line in web.php file, however this catch all getting higher priority and neither control panel nor existing pages showing up.

Is there a possibility to return back custom catch-all view with 200 return code?

set your 404 page to do the search?
