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