• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky nang x hoi. hieu ((qua chat) OR (luan phan)) xuc van ((thanh ca) OR (thanh cac)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky nang x hoi. hieu ((qua chat) or (luan phan)) xuc van ((thanh ca) OR (thanh cac)) cua tre*".
