• If you are trying to use Boolean operators, they must be ALL CAPS: dong hua yang chua wang ((liang dan) OR (liang sun)) ((wong sau) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong hua yang chua wang ((liang dan) OR (liang sun)) ((wong sau) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong hua yang chua wang ((liang dan) OR (liang sun)) ((wong sau) or (song shin)) ;*.
