• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (((yuan wang) OR (yuan chang)))) yang i gene one nan kong (sar OR sara) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (((yuan wang) OR (yuan chang)))) yang i gene one nan kong (sar or sara) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (((yuan wang) OR (yuan chang)))) yang i gene one nan kong (sar or sara) ;*.
