• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yuan) OR (fang yuan)) kai chai dan yang jin ((dang hai) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yuan) OR (fang yuan)) kai chai dan yang jin ((dang hai) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yuan) OR (fang yuan)) kai chai dan yang jin ((dang hai) or (zhong zhi)) ;*.
