• If you are trying to use Boolean operators, they must be ALL CAPS: (lang OR wing) yan yuan ji ((((chen ping) OR (chen wang))) OR (zhen yong)) amin hong shin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(lang or wing) yan yuan ji ((((chen ping) OR (chen wang))) or (zhen yong)) amin hong shin ;~".
• Adding a wildcard symbol may retrieve word variants: (lang or wing) yan yuan ji ((((chen ping) OR (chen wang))) or (zhen yong)) amin hong shin ;*.
