• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu lang) OR (tien lang)) - thanh dung cua thong cong ((dan toan) OR (van toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu lang) OR (tien lang)) - thanh dung cua thong cong ((dan toan) or (van toan)) cau".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu lang) OR (tien lang)) - thanh dung cua thong cong ((dan toan) or (van toan)) cau*.
