• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) sang - ((hanh tung) OR (hanh mang)) cua thuong cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) sang - ((hanh tung) or (hanh mang)) cua thuong cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) sang - ((hanh tung) or (hanh mang)) cua thuong cong tan toan cau*.
