Zerx

Zerx is a search engine that allows visitors to view sites related to another site, or refine your existing search using that site as the basis for a clustered search. The ultimate goal is to bridge the gap between search engine spiders and web directories.

More information about them, from the website:

Currently the Zerx search algorithm is fully functional, and our near term plans are to test out the functionality and to build a database of web sites that will allow Zerx to compete with the major web directories. Eventually the Zerx database of web sites will be expanded to the point of competition with the largest of the web search engines.

Big promises, indeed!
