• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu xanh) OR (chieu sach)) - dinh trong van nhung cong ((dan toan) OR (van toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chieu sach)) - dinh trong van nhung cong ((dan toan) OR (van toan)) cau".
