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