• If you are trying to use Boolean operators, they must be ALL CAPS: (((( yuan yang hui di dati dian wen da xi. ) OR ( yuan yong hui di dati dian wen da xi. ))) OR ( guan huan hui de di san wen da xi. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( yuan yang hui di dati dian wen da xi. ) OR ( yuan yong hui di dati dian wen da xi. ))) or ( guan huan hui de di san wen da xi. ))~".
• Adding a wildcard symbol may retrieve word variants: (((( yuan yang hui di dati dian wen da xi. ) OR ( yuan yong hui di dati dian wen da xi. ))) or ( guan huan hui de di san wen da xi. ))*.
