zhang lei » zhang wei, zhang dai
gang ryan » wang yan, gang yao
yang jui » yang judy, yang xi

• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR lang) ((((yang di) OR (yang jui))) OR (yang yi)) jui cheng zhang lei gang ryan ;~.
• Adding a wildcard symbol may retrieve word variants: (wing or lang) ((((yang di) or (yang jui))) or (yang yi)) jui cheng zhang lei gang ryan ;*.
