• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang fang) OR (wang liang)) yuan yi ((cheng ang) OR (cheng zhang)) making song (shin OR sein) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang fang) OR (wang liang)) yuan yi ((cheng ang) or (cheng zhang)) making song (shin or sein) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang fang) OR (wang liang)) yuan yi ((cheng ang) or (cheng zhang)) making song (shin or sein) ;*.
