Usually I alter static routes in routes subscriber:
protected function alterRoutes(RouteCollection $collection) {
$route = $collection->get('gutenberg.media.load_media');
if ($route) {
$route->setDefault('_controller', 'Drupalgutenberg_advControllerMediaController::loadMedia');
}
}
However I this does not work for routes defined in routes_callback, so this does not work for search route for example:
$route = $collection->get('search.view_node_search');
if ($route) {
$route->setDefault('_controller',
'Drupalwi_miscControllerSearchController::view');
}
So how to alter search route controller?
