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