• If you are trying to use Boolean operators, they must be ALL CAPS: (lang OR wing) ((hyoung yan) OR (kyoung yun)) yuan ting yong li zhang han ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(lang or wing) ((hyoung yan) OR (kyoung yun)) yuan ting yong li zhang han ;~".
• Adding a wildcard symbol may retrieve word variants: (lang or wing) ((hyoung yan) OR (kyoung yun)) yuan ting yong li zhang han ;*.
