• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((chieu xanh) OR (chieu tinh)) - canh tranh cua thong ((phuong danh) OR (duong van)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((chieu xanh) OR (chieu tinh)) - canh tranh cua thong ((phuong danh) or (duong van)) toan cau".
• Adding a wildcard symbol may retrieve word variants: doc ((chieu xanh) OR (chieu tinh)) - canh tranh cua thong ((phuong danh) or (duong van)) toan cau*.
