Multi Search engines
Deeperweb.com – This is my favorite search engine. It breaks your results down into categories – general web, blogs, news, academic, cloud, metrics, research, etc. This allows you to quickly focus on the type of answer you were looking for. Makes my top 10 websites!
Surfwax – They have a 2011 interface for rss and a 2009 interface I think is better. Takes 60 seconds to understand how to use it.
Dogpile – another multi engine aggregator
Scout Project- scout.wisc.edu — Since 1994, the Scout Project has focused on developing better tools and services for finding, filtering, and presenting online information and metadata.
www.findsmarter.com – You can filter the search by domain extension, or by topic which is quite neat. Sources Yahoo, Bing, Wiki, Blekko, and Alltheweb
Cluster Analysis Engine
TouchGraph – A brilliant clustering tool that shows you relationships in your search results using a damn spiffy visualization. The smart way to use it, is to let it help you find new sources to your search topic. I have to add, the wiggly effect on the visualization is damn cool, just grab the center item and move it to understand what I’m talking about. (sometimes it doesn’t wiggle, however. Java issue?)
Yippy.com – A useful, non-graphical clustering of results. Give it 2 minutes of your time to understand how it works and it will give back hours of saved research time. They are actively funded and are acquiring other search tech assets, so worth using.
www.navagent.com/ – Not a web based search engine, requires you download software. Highly rated, very interesting especially to the 35F intel types.
