• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (doi chieu)) xanh - thanh trung uong ((duong cong) OR (duong trong)) danh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (doi chieu)) xanh - thanh trung uong ((duong cong) OR (duong trong)) danh toan cau".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (doi chieu)) xanh - thanh trung uong ((duong cong) OR (duong trong)) danh toan cau*.
