• The words AND, OR and NOT may confuse the search; try adding quotes: "((chan kang) or (chung kang)) hoang ((china rene) OR (china rate)) yang jin hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((chan kang) or (chung kang)) hoang ((china rene) OR (china rate)) yang jin hong yu ;*.
