• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - thanh trung cap nhung cong ((((van toan) OR (van tan))) OR (van than)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - thanh trung cap nhung cong ((((van toan) OR (van tan))) or (van than)) cau*".
