• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - thanh truong dai tuong ((((cong manh) OR (duong manh))) OR (cong thanh)) toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - thanh truong dai tuong ((((cong manh) OR (duong manh))) or (cong thanh)) toan tap".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - thanh truong dai tuong ((((cong manh) OR (duong manh))) or (cong thanh)) toan tap*.
