• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ta hang ((va noi) OR (van noi)). hieu ve cham tuc va ((danh vai) OR (doanh van)) cuu tre~".
• Adding a wildcard symbol may retrieve word variants: su sach ta hang ((va noi) OR (van noi)). hieu ve cham tuc va ((danh vai) OR (doanh van)) cuu tre*.
