• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) yan ((yuan li) OR (guan li)) ((chin chang) OR (china zhang)) min jeong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) yan ((yuan li) or (guan li)) ((chin chang) OR (china zhang)) min jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) yan ((yuan li) or (guan li)) ((chin chang) OR (china zhang)) min jeong shu ;*.
