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