• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (hoc hien)) xanh - thanh truong can bang cong ((tan toan) OR (van toan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (hoc hien)) xanh - thanh truong can bang cong ((tan toan) OR (van toan)) cao".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (hoc hien)) xanh - thanh truong can bang cong ((tan toan) OR (van toan)) cao*.
