• If you are trying to use Boolean operators, they must be ALL CAPS: wang yanling ((dan phan) OR (man han)) ((china chang) OR (china changqi)) hong hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling ((dan phan) or (man han)) ((china chang) OR (china changqi)) hong hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling ((dan phan) or (man han)) ((china chang) OR (china changqi)) hong hong yu ;*.
