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