• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong wang ((yang tan) OR (yang yang)) hong jong ((fang hay) OR (eang hay)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong wang ((yang tan) or (yang yang)) hong jong ((fang hay) OR (eang hay)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong wang ((yang tan) or (yang yang)) hong jong ((fang hay) OR (eang hay)) ;*.
