• If you are trying to use Boolean operators, they must be ALL CAPS: ((yiqian wang) OR (yuan chang)) yang ((hua can) OR (arua can)) hong hai kong sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yiqian wang) or (yuan chang)) yang ((hua can) OR (arua can)) hong hai kong sar ;~".
• Adding a wildcard symbol may retrieve word variants: ((yiqian wang) or (yuan chang)) yang ((hua can) OR (arua can)) hong hai kong sar ;*.
