• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (so sach)) ky nang ((x hoi) OR (x ho)). hieu du chat xuc van dinh viet cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (so sach)) ky nang ((x hoi) OR (x ho)). hieu du chat xuc van dinh viet cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu cach) or (so sach)) ky nang ((x hoi) OR (x ho)). hieu du chat xuc van dinh viet cua tre*.
