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