• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan clan) OR (kang chen)) sun ((japan ying) OR (japan using)) king kong sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan clan) or (kang chen)) sun ((japan ying) OR (japan using)) king kong sar ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan clan) or (kang chen)) sun ((japan ying) OR (japan using)) king kong sar ;*.
