• If you are trying to use Boolean operators, they must be ALL CAPS: cho chu xanh - ((hang hang) OR (hung thang)) va thang ((long doan) OR (dong doanh)) chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho chu xanh - ((hang hang) or (hung thang)) va thang ((long doan) OR (dong doanh)) chan cau~".
• Adding a wildcard symbol may retrieve word variants: cho chu xanh - ((hang hang) or (hung thang)) va thang ((long doan) OR (dong doanh)) chan cau*.
