• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach tien thuat sach ha thu thong ) OR ( tu sach tri ((te cau) OR (te cao)) hoa phan cong ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach tien thuat sach ha thu thong ) or ( tu sach tri ((te cau) OR (te cao)) hoa phan cong ))~".
• Adding a wildcard symbol may retrieve word variants: (( te sach tien thuat sach ha thu thong ) or ( tu sach tri ((te cau) OR (te cao)) hoa phan cong ))*.
