• If you are trying to use Boolean operators, they must be ALL CAPS: wan hyoung tang ((jin song) OR (kim song)) ((yang xi) OR (yang jui)) zhang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan hyoung tang ((jin song) OR (kim song)) ((yang xi) or (yang jui)) zhang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wan hyoung tang ((jin song) OR (kim song)) ((yang xi) or (yang jui)) zhang hai ;*.
