• If you are trying to use Boolean operators, they must be ALL CAPS: ((chen wang) OR (chen rong)) ((yang xi) OR (yang jui)) chen zheng xin kong sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((chen wang) OR (chen rong)) ((yang xi) or (yang jui)) chen zheng xin kong sar ;~".
• Adding a wildcard symbol may retrieve word variants: ((chen wang) OR (chen rong)) ((yang xi) or (yang jui)) chen zheng xin kong sar ;*.
