• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - ((thanh trung) OR (((thanh tung) OR (thanh cong)))) va phuong cong sang tao cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - ((thanh trung) or (((thanh tung) OR (thanh cong)))) va phuong cong sang tao cap~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - ((thanh trung) or (((thanh tung) OR (thanh cong)))) va phuong cong sang tao cap*.
