• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yan) OR (ying jin))) OR (((yang yi) OR (yang di))))let a ta chen shuang boon chong c ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang yan) or (ying jin))) or (((yang yi) or (yang di))))let a ta chen shuang boon chong c ;*.
