• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hieu cach - ((thanh tuong) OR (thanh huong)) cua ((dang duong) OR (dang dung)) van tuan mau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hieu cach - ((thanh tuong) OR (thanh huong)) cua ((dang duong) or (dang dung)) van tuan mau*".
