• If you are trying to use Boolean operators, they must be ALL CAPS: ((((nan yan) OR (qian yan))) OR (kang young)) yang juan ke yan guan long shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((nan yan) OR (qian yan))) or (kang young)) yang juan ke yan guan long shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((((nan yan) OR (qian yan))) or (kang young)) yang juan ke yan guan long shu ;*.
