• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (doc hieu)) sach - thanh ((truong quan) OR (trong quan)) nhung cuong tap quan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (doc hieu)) sach - thanh ((truong quan) or (trong quan)) nhung cuong tap quan tap~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (doc hieu)) sach - thanh ((truong quan) or (trong quan)) nhung cuong tap quan tap*.
