• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((dieu hanh) or (thien thanh)) - canh manh cua ((dung phuong) OR (dung chung)) van thanh cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((dieu hanh) or (thien thanh)) - canh manh cua ((dung phuong) OR (dung chung)) van thanh cau*.
