Abstract

Commercial search engines were put to a test as we searched the online Wikipedia which is a newer version of the INEX 2010 document collection. Although the INEX 2010 ad hoc search tasks and the search features of the public search engines are not 100% compatible, we were able to compare and evaluate the search results of online search engines with INEX 2010 topics, assessments, and metrics. Considering the first page of results, we cannot see a big difference between the performance of the best academic search engines and the best commercial ones. Of the public search engines, Google and Yahoo perform marginally better than Bing and significantly better than the on-site Wikipedia search.
