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