• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((thieu sach) OR (chieu sach)) - anh dung cua hang ((cong ban) OR (cong bang)) thai cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thieu sach) OR (chieu sach)) - anh dung cua hang ((cong ban) or (cong bang)) thai cac~".
• Adding a wildcard symbol may retrieve word variants: toc ((thieu sach) OR (chieu sach)) - anh dung cua hang ((cong ban) or (cong bang)) thai cac*.
