• If you are trying to use Boolean operators, they must be ALL CAPS: hoc kien sach - nhanh mang va nhung huong ((((dan than) OR (van than))) OR (ban than)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc kien sach - nhanh mang va nhung huong ((((dan than) OR (van than))) or (ban than)) cau".
