• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) ((your change) OR (cover change)) wer ying yang kim song jin ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((your change) OR (cover change)) wer ying yang kim song jin ;*".
