• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang ((o hoi) OR (x ho)). hieu ve ((cham xuc) OR (chat xuc)) va hanh doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang ((o hoi) or (x ho)). hieu ve ((cham xuc) OR (chat xuc)) va hanh doi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang ((o hoi) or (x ho)). hieu ve ((cham xuc) OR (chat xuc)) va hanh doi cua tre*.
