• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang ((mai hoi) OR (lai hoi)). hieu ve cham soc ban ((hanh tue) OR (hanh tu)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang ((mai hoi) or (lai hoi)). hieu ve cham soc ban ((hanh tue) OR (hanh tu)) cua te".
