• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hieu manh) OR (thien anh)) - canh doanh cua thuong ((cong dan) OR (huong dan)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) or (thien anh)) - canh doanh cua thuong ((cong dan) OR (huong dan)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (thien anh)) - canh doanh cua thuong ((cong dan) OR (huong dan)) phan cau*.
