Last month a there was a discussion over at Search Engine Watch about running a test to see which search engine produces the most relevant results. You can view Barry Schwartz’s blog on the same topic as well.
Yesterday Barry announced that he has completed a search engine that does just that. His new RustySearch allows you to perform a search which randomly pulls data from the top 4 engines. You can then rate each listing for relevance to your query. Results will be tabulated and Barry will provide a relevance score based on users ratings.
