• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan guan li chih chen rong ((((chong shu) OR (cong shu))) OR (((cong sun) OR (wing sun)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan guan li chih chen rong ((((chong shu) or (cong shu))) or (((cong sun) OR (wing sun)))) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan guan li chih chen rong ((((chong shu) or (cong shu))) or (((cong sun) OR (wing sun)))) ;*.
