• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach ((che de) OR (chen den)) giai con hong tien ) OR ( thu sach cha me gioi van phong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach ((che de) OR (chen den)) giai con hong tien ) or ( thu sach cha me gioi van phong tin ))".
