• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang ying ((hua rene) OR (juan rene)) ((yan jiu) or (((yang jin) or (yang jun)))) hong ng ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang ying ((hua rene) OR (juan rene)) ((yan jiu) or (((yang jin) or (yang jun)))) hong ng ;*.
