    This chapter presents a theoretical framework for evaluating next generation search engines. We focuson search engines whose results presentation is enriched with additional information and does notmerely present the usual list of “10 blue links”, that is, of ten links to results, accompanied by a shortdescription. While Web search is used as an example here, the framework can easily be applied tosearch engines in any other area.The framework not only addresses the results presentation, but also takes into account an extension ofthe general design of retrieval effectiveness tests. The chapter examines the ways in which this designmight influence the results of such studies and how a reliable test is best designed
