• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang yang yi ((dai sang) OR (di san)) minh ((cong shu) OR (gong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang yang yi ((dai sang) OR (di san)) minh ((cong shu) or (gong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang yang yi ((dai sang) OR (di san)) minh ((cong shu) or (gong hui)) ;*.
