• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu xanh) OR (hieu lang))) OR (chieu tinh)) - hanh trang va thong cong tap doan va~.
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu xanh) or (hieu lang))) or (chieu tinh)) - hanh trang va thong cong tap doan va*.
