• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((thieu sach) OR (chieu sach)) - thanh trung ((tuan dang) OR (tran dang)) luong giao thi cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thieu sach) OR (chieu sach)) - thanh trung ((tuan dang) or (tran dang)) luong giao thi cap".
• Adding a wildcard symbol may retrieve word variants: toc ((thieu sach) OR (chieu sach)) - thanh trung ((tuan dang) or (tran dang)) luong giao thi cap*.
