• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan fang) OR (wang yang)) yuan zi chen cheng ling ((hong seo) OR (wong shiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan fang) OR (wang yang)) yuan zi chen cheng ling ((hong seo) or (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan fang) OR (wang yang)) yuan zi chen cheng ling ((hong seo) or (wong shiu)) ;*.
