• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang ((o hai) OR (co hai)). hieu ve cac xuc van anh thai ((cuu tre) OR (cua tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang ((o hai) or (co hai)). hieu ve cac xuc van anh thai ((cuu tre) OR (cua tre))".
