• If you are trying to use Boolean operators, they must be ALL CAPS: thu sang ky nang ((x hoi) OR (o hoi)). hieu ve cam duc va thanh thai ((cua chu) OR (sua chua)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sang ky nang ((x hoi) or (o hoi)). hieu ve cam duc va thanh thai ((cua chu) OR (sua chua))".
