• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang yang hua rent sharing mining ((((chong yun) OR (chang yun))) or (chen yiqun)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang yang hua rent sharing mining ((((chong yun) OR (chang yun))) or (chen yiqun)) ;*.
