• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chiet tach)) - canh vang ((cua dang) OR (cua cong)) cong tan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chiet tach)) - canh vang ((cua dang) OR (cua cong)) cong tan toan cau".
