• If you are trying to use Boolean operators, they must be ALL CAPS: ho hieu quang - ((thanh tuong) OR (thanh huong)) va thong thong ((danh van) OR (dang van)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho hieu quang - ((thanh tuong) OR (thanh huong)) va thong thong ((danh van) or (dang van)) ban~".
• Adding a wildcard symbol may retrieve word variants: ho hieu quang - ((thanh tuong) OR (thanh huong)) va thong thong ((danh van) or (dang van)) ban*.
