The search engine for research
"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. It excludes not only obvious spam sites, but also marginal sites that read well, but lack academic or journalistic rigor. As importantly, the very best Web sites that are often buried on other search engines appear on the first page of SweetSearch results."
KidRex searches emphasize kid-related webpages from across the entire web and are powered by Google Custom Search™ and use Google SafeSearch™ technology.
