• If you are trying to use Boolean operators, they must be ALL CAPS: wang qian yan li ((((chen zheng) OR (chen aizheng))) OR (cheng zhang)) min jeong shu ;~.
• Adding a wildcard symbol may retrieve word variants: wang qian yan li ((((chen zheng) or (chen aizheng))) or (cheng zhang)) min jeong shu ;*.
