• If you are trying to use Boolean operators, they must be ALL CAPS: ((((ho chieu) OR (theo chu))) OR (mot chieu)) sach - hanh trinh va nhung cong dan toan tap~.
• Adding a wildcard symbol may retrieve word variants: ((((ho chieu) or (theo chu))) or (mot chieu)) sach - hanh trinh va nhung cong dan toan tap*.
