• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) or (chieu xanh)) - thanh trung tuan thong hoang ((van hanh) OR (van anh)) cac~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (chieu xanh)) - thanh trung tuan thong hoang ((van hanh) OR (van anh)) cac*.
