2 What’s Alta Vista AltaVista was one of the three largest and most important search engines for many years, but it is no longer as popular as it used to be.largest It had two distinct search modes: Basic Search and Advanced Search. In August 2000, it introduced a third: the Power Search.Basic Search Advanced Search In Feb. 2002, the Power Search features were added to the Advanced Search page and then in Nov. 2002 were also moved to the More Precision page.More Precision There are some significant differences between the Basic and Advanced search pages. In Feb. 2003, AltaVista was bought by Overture. Overture expected to merge the AltaVista and AlltheWeb databases later in 2003, but once Yahoo! bought Overture, AltaVista's database was replaced by a Yahoo!/Inktomi on March 25, 2004.bought by Overture
