• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yang ((xi best) OR (i best)) ying shin ((dong skin) OR (dong sin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang ((xi best) or (i best)) ying shin ((dong skin) OR (dong sin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yang ((xi best) or (i best)) ying shin ((dong skin) OR (dong sin)) ;*.
