How to display search results in alphabetical order?

Hi,

I am searching a custom post type named seed_companies and would like to display the results in alphabetical order (ASC). I tried adding this code to my functions.php but it didn’t work.

function custom_order_search_results($query) {
    if (!is_admin() && $query->is_main_query() && $query->is_search() && $query->get('post_type') === 'seed_companies') {

        $query->set('order', 'ASC');
        
        $query->set('orderby', 'title');
    }
}

add_action('pre_get_posts', 'custom_order_search_results');

Is there a better way to do this?

Thank you!
