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