• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((yan wang) OR (yuan wang)) lin lu ((gong min) OR (song ming)) ((long du) OR (long d)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((yan wang) or (yuan wang)) lin lu ((gong min) or (song ming)) ((long du) OR (long d)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((yan wang) or (yuan wang)) lin lu ((gong min) or (song ming)) ((long du) OR (long d)) ;*.
