• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y tang ((ma hoi) OR (ma hoa)). hieu ((va cham) OR (va tham)) xuc va dan dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y tang ((ma hoi) or (ma hoa)). hieu ((va cham) OR (va tham)) xuc va dan dai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y tang ((ma hoi) or (ma hoa)). hieu ((va cham) OR (va tham)) xuc va dan dai cua tre*.
