• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach dung ai gia tuong ) OR ((( tu bac ((tinh bi) OR (tinh vi)) gia cong ) OR ((( tu bach kinh bai giai tuong ) OR ( tu ((((cach kinh) OR (cac tinh))) OR (tich kinh)) bai giang duong ))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach dung ai gia tuong ) or ((( tu bac ((tinh bi) OR (tinh vi)) gia cong ) or ((( tu bach kinh bai giai tuong ) or ( tu ((((cach kinh) or (cac tinh))) or (tich kinh)) bai giang duong ))))))~".
• Adding a wildcard symbol may retrieve word variants: (( te sach dung ai gia tuong ) or ((( tu bac ((tinh bi) OR (tinh vi)) gia cong ) or ((( tu bach kinh bai giai tuong ) or ( tu ((((cach kinh) or (cac tinh))) or (tich kinh)) bai giang duong ))))))*.
