• If you are trying to use Boolean operators, they must be ALL CAPS: theo tieu sach - ((canh tranh) OR (hoang xanh)) hua khong tuong van ((thanh ban) OR (thanh van)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu sach - ((canh tranh) or (hoang xanh)) hua khong tuong van ((thanh ban) OR (thanh van))".
