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