subdomain is lost on redirect()->to()

Have you tried using

PHP Code:

current_url() 


which will return the full url (including segments that you can strip out) in your redirect statement?

So it could possibly look like this:

PHP Code:

$url =  str_replace("/unwanted/segments", "/search", current_url());

retrun redirect()->to($url);

//or if you have no segments

$url = current_url() . "/search";

return redirect()->to($url);
