• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang ((mai hoi) OR (lai hoi)). hieu va ((cham xuc) OR (cam xuc)) gia thanh va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang ((mai hoi) OR (lai hoi)). hieu va ((cham xuc) or (cam xuc)) gia thanh va cua tre*".
