通过标签搜索产品

Question

我正在使用下面的代码按产品倾斜搜索产品，但我也想包括按产品标签搜索，因此标题和标签都将包含

function __search_by_title_only( $search, $wp_query )
{
    global $wpdb;
    if(empty($search)) {
    return $search; // skip processing - no search term in query
}
$q = $wp_query->query_vars;
$n = !empty($q['exact']) ? '' : '%';
$search =
$searchand = '';
foreach ((array)$q['search_terms'] as $term) {
    $term = esc_sql($wpdb->esc_like($term));
    $search .= "{$searchand}($wpdb->posts.post_title LIKE '{$n}{$term}{$n}')";
    $searchand = ' AND ';
}
if (!empty($search)) {
    $search = " AND ({$search}) ";
    if (!is_user_logged_in())
        $search .= " AND ($wpdb->posts.post_password = '') ";
}
return $search;
}
add_filter('posts_search', '__search_by_title_only', 500, 2);

预先感谢
