  Mettrop, W. ; Nieuwenhuysen, P.: Internet search engines : fluctuations in document accessibility.
  In: Journal of documentation. 57(2001) no.5, S.623-651.
  
  Abstract: An empirical investigation of the consistency of retrieval through Internet search engines is reported. Thirteen engines are evaluated: AltaVista, EuroFerret, Excite, HotBot, InfoSeek, Lycos, MSN, NorthernLight, Snap, WebCrawler and three national Dutch engines: Ilse, Search.nl and Vindex. The focus is on a characteristics related to size: the degree of consistency to which an engine retrieves documents. Does an engine always present the same relevant documents that are, or were, available in its databases? We observed and identified three types of fluctuations in the result sets of several kinds of searches, many of them significant. These should be taken into account by users who apply an Internet search engine, for instance to retrieve as many relevant documents as possible, or to retrieve a document that was already found in a previous search, or to perform scientometric/bibliometric measurements. The fluctuations should also be considered as a complication of other research on the behaviour and performance of Internet search engines. In conclusion: in view of the increasing importance of the Internet as a publication/communication medium, the fluctuations in the result sets of Internet search engines can no longer be neglected.

  Laan, H. van der: Nieuwe Nederlandse Web-Woelers.
  In: Informatie professional. 2(1998) no.3, S.34-35.
  
  Abstract: In the Netherlands updated versions of the Vindex and Zoek search engines have been released. Vindex indexes sites originating in the Netherlands and us currently undergoing a 6-month trial period. In both search engines help for users is unclear whilst truncation practice in Zoek is unhelpful. However, Zoek offers a range of options including ranking of topics. Display of search results is excellent
