• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - thanh tung cua thong ((cong tan) OR (cong tac)) ((thanh cac) OR (nhanh bac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - thanh tung cua thong ((cong tan) OR (cong tac)) ((thanh cac) or (nhanh bac))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - thanh tung cua thong ((cong tan) OR (cong tac)) ((thanh cac) or (nhanh bac))*.
