• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wan) jia fang a ((((china changqi) OR (chin chang))) OR (china chang)) lai cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) jia fang a ((((china changqi) OR (chin chang))) or (china chang)) lai cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) jia fang a ((((china changqi) OR (chin chang))) or (china chang)) lai cong shu ;*.
