Korbinian Hartl examines the roles of search engines within the constitutional order. Dogmatically, the author first investigates the positioning of search engines within the fundamental rights of communication, and then addresses the question of whether there is an obligation for the legislator to react to existing potential effects. The conclusion involves a discussion of regulatory options de lege ferenda. Within the constitutional order, search engines are not viewed merely as technical 'document collectors,' but as central entities endowed with their own power of influence.
