• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ha nang ((ma hoi) OR (ma hoa)). hieu ve ((cham xuc) OR (cam xuc)) ban thanh di cau tren".
• Adding a wildcard symbol may retrieve word variants: su sach ha nang ((ma hoi) OR (ma hoa)). hieu ve ((cham xuc) OR (cam xuc)) ban thanh di cau tren*.
