• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang yan lin ((li song) OR (((yun song) OR (yun young)))) minh long shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang yan lin ((li song) or (((yun song) OR (yun young)))) minh long shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang yan lin ((li song) or (((yun song) OR (yun young)))) minh long shu ;*.
