• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong yang) OR (yang yang))) OR (dong skin)) ya hua rene yuan ting ((tong hui) OR (gong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong yang) OR (yang yang))) or (dong skin)) ya hua rene yuan ting ((tong hui) or (gong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((((dong yang) OR (yang yang))) or (dong skin)) ya hua rene yuan ting ((tong hui) or (gong hui)) ;*.
