I need to take a short break from the session about search and EMC. I came across this entry in the blogosphere:

The Top 100 Alternative Search Engines by Written by Charles Knight, AltSearchEngines editor / January 29, 2007 2:34 AM

To be very honest with you, I don’t use nor have I tried all of these different engines.  I think they actually validate my other points, that you should use the engine and technique for the problem at hand.  Some of them are fun to play with (although Ms. Dewey is a bit loud for work) and they (for the most part) variously demonstrate the basic items about search – user interaction and visualization, keywords, ranking, relevancy, clustering, relationship tracking, social search, etc.

I think I will have to add in a whole posting thread about the engines listed; not to duplicate what Mr. Knight has done but hopefully to extend it.

Take a look and see for yourself.  Enjoy.
