• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien sang) OR (hien trang)) - doanh doanh xua thang nong ((dan thanh) OR (dang thanh)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien sang) or (hien trang)) - doanh doanh xua thang nong ((dan thanh) OR (dang thanh)) ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien sang) or (hien trang)) - doanh doanh xua thang nong ((dan thanh) OR (dang thanh)) ban*.
