• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) sang - hanh ((trung cua) OR (tran tuan)) nhung cong tan toan tap~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) sang - hanh ((trung cua) or (tran tuan)) nhung cong tan toan tap*.
