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