• If you are trying to use Boolean operators, they must be ALL CAPS: ((yuan kang) OR (huang bin)) jaan hui gene yang jin ((hong shu) OR (cong shu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan kang) or (huang bin)) jaan hui gene yang jin ((hong shu) OR (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan kang) or (huang bin)) jaan hui gene yang jin ((hong shu) OR (cong shu)) ;*.
