Sweet Search "searches only the 35,000 Web sites that our staff of research experts and librarians and teachers have evaluated and approved. We constantly evaluate our search results and "fine-tune" them, by increasing the ranking of Web sites from organizations such as the Library of Congress, the Smithsonian, PBS and university Web sites.
SweetSearch helps students find outstanding information, faster. It enables them to determine the most relevant results from a list of credible resources, and makes it much easier for them to find primary sources. We exclude not only obvious spam sites, but also marginal sites that read well, but lack academic or journalistic rigour. As importantly, the very best Web sites that are often buried on other search engines appear on the first page of SweetSearch results."
