• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tach - ((hanh trang) OR (thanh trung)) cac thuong ((cong san) OR (cong ty)) toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tach - ((hanh trang) OR (thanh trung)) cac thuong ((cong san) or (cong ty)) toan cao*".
