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