• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (vu sach)) ky hang va hoi. thien van cam luc va hanh va ((cau tren) OR (cu tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (vu sach)) ky hang va hoi. thien van cam luc va hanh va ((cau tren) OR (cu tren))*".
