• If you are trying to use Boolean operators, they must be ALL CAPS: (( yuan ong hui de david chan neng ((yan xi) OR (yuan xi)). ) OR ( yuan ong hui de ji san wen da xi. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( yuan ong hui de david chan neng ((yan xi) OR (yuan xi)). ) or ( yuan ong hui de ji san wen da xi. ))~".
• Adding a wildcard symbol may retrieve word variants: (( yuan ong hui de david chan neng ((yan xi) OR (yuan xi)). ) or ( yuan ong hui de ji san wen da xi. ))*.
