http://clusty.com/ I can't tell if it's based upon other search engine's results or is crawling on its own. What are your thoughts?
Another meta search engine is right How many search engines are out there beside google, yahoo, live and ask?
Yes, I made a couple queries and it extracts from other search engines. There are actually few engines worldwide that actually have their own search engine crawler spider technology, spidering servers, and cache/storage databases to store 10's of millions of websites info. Its not as simple as crawling the www and storing the data. The key to Google is its ability to analyze every aspect of their spidered data to provide users with only relevant results.
It looks like your engine is dead (but you are now banned for whatever reason, so you probably do not care).
