• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu tinh)) - ((thanh thang) OR (tthanh thang)) van thong cong san than cao~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu tinh)) - ((thanh thang) or (tthanh thang)) van thong cong san than cao*.
