Google’s announcement today: the Google Search Appliance (for indexing and searching on server environments) has just added clustering to the results. It shouldn’t be too long before we see it filtering (ahem) down to the web search realm.
Clustering is not new; to see it in action check out Vivisimo’s Clusty search engine. I have long thought that, as long as it remains user-friendly (and usable) clustering is a fantastic way of narrowing searches.
