• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ty sang tao hoi. hieu su cham soc ((ban thanh) OR (va danh)) lai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ty sang tao hoi. hieu su cham soc ((ban thanh) or (va danh)) lai cua te~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ty sang tao hoi. hieu su cham soc ((ban thanh) or (va danh)) lai cua te*.
