Wordpress exclude categories from search

You can edit functions.php and add something like the following

function search_excl_expired_cat ($query) { if ($query->is_admin) return $query; if ($query->is_search) { $query->set('category__not_in', array(233, 234)); // cat id } return $query; } add_filter('pre_get_posts', 'search_excl_expired_cat'); http://stanislav.it/exclude-a-category-from-wordpress-search-results/
