• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky dong ((hoa hoi) OR (hoa hoc)). hieu tuc cham xuc van tuan ((va chu) OR (va cau)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky dong ((hoa hoi) or (hoa hoc)). hieu tuc cham xuc van tuan ((va chu) OR (va cau)) tre~".
• Adding a wildcard symbol may retrieve word variants: so sach ky dong ((hoa hoi) or (hoa hoc)). hieu tuc cham xuc van tuan ((va chu) OR (va cau)) tre*.
