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