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