• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (ho chieu)) sang - thanh dung cuc phuong thong den ((toan cao) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (ho chieu)) sang - thanh dung cuc phuong thong den ((toan cao) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (ho chieu)) sang - thanh dung cuc phuong thong den ((toan cao) or (van ban))*.
