• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang tang) OR (wang liang)) min yuan yi ((gang xi) OR (yang xi)) tang zheng ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang tang) or (wang liang)) min yuan yi ((gang xi) OR (yang xi)) tang zheng ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang tang) or (wang liang)) min yuan yi ((gang xi) OR (yang xi)) tang zheng ;*.
