• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ky nang ((o hoc) OR (co hai)). hieu ve cac xuc van khanh thai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ky nang ((o hoc) or (co hai)). hieu ve cac xuc van khanh thai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ky nang ((o hoc) or (co hai)). hieu ve cac xuc van khanh thai cuu tre*.
