Refseek started in 2008 and was developed by Rick Gottlieb. Since 2015 (or earlier), Refseek has been using Google Custom Search. There isn't much to find about the previously underlying search technology. As far as can be seen, scientific offers such as CiteSeerX and Arxiv were originally searched. In addition, a Mathcalculator was offered, which is still listed in the search tips today, but no longer works. Today two searches based on the Google user-defined search are offered. The ebsuche is limited to eb pages with the extension org, gov, edu, The document search searches specifically for PDF documents.

»Refseek is an academic search engine which is simpler than Google even in appearance. Refseek does not claim to offer more results than Google. Instead, it removes results that are not related to science, academia and research. The best thing about Refseek is that you can search for information related to your subject without getting distracted by sponsored links.With a database of over 1 billion documents, web pages, books, journals, newspapers, online encyclopedias and articles, Refseek is your ultimate companion for academic research. « Source

» RefSeek: This academic search engine will help you find useful reference material from predominately .edu, .org and .gov sites.« Source


Critical points

»Since the search engine is powered by Google, the search engine also adds unneeded ads to websites that are unrelated to your subject.« Source
