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