When user search and there is no results found wordpress still return 200 OK. I want to change it to 404 Not Found. Is it possible to return 404 Not Found header in search.php? If yes, how to do that?.
Thanks.
How to return HTTP 404 when no search results found?
It’s bad practice to do so purely because the Search Results page was found it just returned no results.
A 404 would be used if the search page didn’t exist.
