• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) sang - ((hanh dinh) OR (thanh dinh)) cua trong cong san toan cau~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) sang - ((hanh dinh) or (thanh dinh)) cua trong cong san toan cau*.
