• If you are trying to use Boolean operators, they must be ALL CAPS: long tan han chang chen yang john ((song sein) OR (((song jin) OR (song min)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "long tan han chang chen yang john ((song sein) or (((song jin) OR (song min)))) ;~".
• Adding a wildcard symbol may retrieve word variants: long tan han chang chen yang john ((song sein) or (((song jin) OR (song min)))) ;*.
