• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((thieu sach) OR (chieu sach)) - thanh dung cua ((thuong dung) OR (thong dung)) san ca cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thieu sach) or (chieu sach)) - thanh dung cua ((thuong dung) OR (thong dung)) san ca cau".
• Adding a wildcard symbol may retrieve word variants: toc ((thieu sach) or (chieu sach)) - thanh dung cua ((thuong dung) OR (thong dung)) san ca cau*.
