• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ky sang ((tao hoi) OR (tao khoi)). hieu ve cham soc van thanh de cua vat~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (thu sach)) ky sang ((tao hoi) or (tao khoi)). hieu ve cham soc van thanh de cua vat~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (thu sach)) ky sang ((tao hoi) or (tao khoi)). hieu ve cham soc van thanh de cua vat*.
