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