Members of the New York City Company of Friends group recently exchanged a series of emails about new search engines they use. Here are their recommendations:

• Vivisimo: Using a "clustering engine," the service automatically organizes and categorizes similar search results
• Kartoo: This amazing tool queries a number of search engines and represents the collated results in an interactive map that shows how your results group visually. Very cool!
• Teoma: Groups your search results in three categories, including relevant Web pages, suggestions for query refinements, and sites recommended by experts

I'll be returning to these, for sure.
