• If you are trying to use Boolean operators, they must be ALL CAPS: dong wang yang hsu ((chin wang) OR (chen wang)) yanling ((wong sam) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong wang yang hsu ((chin wang) OR (chen wang)) yanling ((wong sam) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong wang yang hsu ((chin wang) OR (chen wang)) yanling ((wong sam) or (wong siu)) ;*.
