• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - ((thanh thuong) OR (thanh chuong)) va trong huong ((dan toan) OR (dan than)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - ((thanh thuong) OR (thanh chuong)) va trong huong ((dan toan) or (dan than)) cau*".
