• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chiet tach)) - thanh tuong ((va trong) OR (va tuong)) cong ban than cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chiet tach)) - thanh tuong ((va trong) or (va tuong)) cong ban than cap*".
