• If you are trying to use Boolean operators, they must be ALL CAPS: wang xuan yang 3 ((chin chang) OR (china chang)) tan ((hong shu) OR (wong shiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang xuan yang 3 ((chin chang) or (china chang)) tan ((hong shu) OR (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang xuan yang 3 ((chin chang) or (china chang)) tan ((hong shu) OR (wong shiu)) ;*.
