• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"((((dan OR dann) OR dannk) OR dank) OR (seine OR den)) (ein\\" OR (deiner\\" OR seinen\\"))\"".
• Removing quotes may allow a broader search: ((((dan OR dann) OR dannk) OR dank) OR (seine OR den)) (ein OR (deiner OR seinen )).
