• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach danh dai giao tuong ) OR ((( ((tu sach) OR (vu sach)) kinh bai giai tuong ) OR ((( ((tu sach) OR (vu sach)) kinh ((bac giai) OR (cac giai)) thuong ) OR ( su sach kinh bac dai tuong ))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach danh dai giao tuong ) or ((( ((tu sach) OR (vu sach)) kinh bai giai tuong ) or ((( ((tu sach) OR (vu sach)) kinh ((bac giai) or (cac giai)) thuong ) or ( su sach kinh bac dai tuong ))))))~".
• Adding a wildcard symbol may retrieve word variants: (( te sach danh dai giao tuong ) or ((( ((tu sach) OR (vu sach)) kinh bai giai tuong ) or ((( ((tu sach) OR (vu sach)) kinh ((bac giai) or (cac giai)) thuong ) or ( su sach kinh bac dai tuong ))))))*.
