• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) xiaodong yu hua dan yang ((jin hong) or (((jin song) OR (john song)))) hai ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) xiaodong yu hua dan yang ((jin hong) or (((jin song) OR (john song)))) hai ;*.
