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