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