• If you are trying to use Boolean operators, they must be ALL CAPS: yuan wang yang li gene long thanh ((wong shiu) OR (((wong sam) OR (wong sau)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan wang yang li gene long thanh ((wong shiu) or (((wong sam) OR (wong sau)))) ;~".
• Adding a wildcard symbol may retrieve word variants: yuan wang yang li gene long thanh ((wong shiu) or (((wong sam) OR (wong sau)))) ;*.
