• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan huan) OR (yan yuan)) jie chen gong min ((wong shiu) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan huan) or (yan yuan)) jie chen gong min ((wong shiu) OR (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan huan) or (yan yuan)) jie chen gong min ((wong shiu) OR (song shin)) ;*.
