change wordpress search url – without 404 not found

Hi
i need a code to change wordpress search url from

https://localhost/wordpress/?s=daniel

to

https://localhost/wordpress/search/daniel

i have this code

function change_search_url_rewrite() {
    if ( is_search() && ! empty( $_GET['s'] ) ) {
        wp_redirect( home_url( "/search/" ) . urlencode( get_query_var( 's' ) ) );
        exit();
    }
}
add_action( 'template_redirect', 'change_search_url_rewrite' );

but when i search

<a href="">daniel</a>

the browser says 404 not found

this code has a .htaccess

RewriteCond %{QUERY_STRING} \\?s=([^&]+) [NC]
RewriteRule ^$ /search/%1/? [NC,R,L]

but it does’nt work

i make a .htaccess it my theme folder
