• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - doanh doanh ((cua dong) OR (hoa dong)) phong va toan ban~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sach)) - doanh doanh ((cua dong) or (hoa dong)) phong va toan ban*.
