• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - canh ((trinh van) OR (trinh vant)) nhung song van ((nhan tai) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - canh ((trinh van) or (trinh vant)) nhung song van ((nhan tai) or (toan tap))*.
