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