• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((chu xanh) OR (chua xang)) - anh dung luan hung cong ((nhan toan) OR (thanh toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chu xanh) or (chua xang)) - anh dung luan hung cong ((nhan toan) OR (thanh toan)) cau".
• Adding a wildcard symbol may retrieve word variants: cho ((chu xanh) or (chua xang)) - anh dung luan hung cong ((nhan toan) OR (thanh toan)) cau*.
