• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu hang ((va hoi) OR (xa hoi)). hieu ((va cai) OR (va cao)) duc va danh lai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu hang ((va hoi) OR (xa hoi)). hieu ((va cai) or (va cao)) duc va danh lai cua te*".
