• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((fang yuan) or (nan yan)) li chen jiageng ((xin song) OR (kim song)) shin ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((fang yuan) or (nan yan)) li chen jiageng ((xin song) OR (kim song)) shin ;*.
