• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (dong skin)) ya hua ((feng juan) OR (meng yuan)) min hong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (dong skin)) ya hua ((feng juan) OR (meng yuan)) min hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (dong skin)) ya hua ((feng juan) OR (meng yuan)) min hong shu ;*.
