Tired of Googleing? Looking for the next big thing in search. Try Clusty.
“But what really makes Clusty unique is what happens after you search. Instead of delivering millions of search results in one long list, our search engine groups similar results together into clusters. Clusters help you see your search results by topic so you can hone in on exactly what you’re looking for or discover unexpected relationships between items. When was the last time you went to the third or fourth page of the search results? Rather than scrolling through page after page, the clusters help you find results you may have missed or that were buried deep in the ranked list.”
Give it a try. Live on the edge. Clusty entry for your Firefox search box.
