• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sach) OR (cuon sach)) - ((manh trung) OR (manh hung)) cap dang cong vang toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sach) or (cuon sach)) - ((manh trung) OR (manh hung)) cap dang cong vang toan tap*".
