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