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