In her interesting presentation for NOLUG at the Oslo College yesterday, Marydee Ojala mentioned that Google and Yahoo were so displeased with the wonderfully named Yagoohoogle , that its owner has obliged by renaming it Twingine (note that a similar service, Yahoogle, is still out there, whatever G and Y may feel about it) Marydee showed us some other interesting multiple engine services: www.jux2.com searches in G, Y, and M, and displays the distribution of results between the three engines. And ranking.thumbshots.com is neat, but only works in IE. It compares searches (2 at a time) between alltheweb, altavista, teoma, wisenut, google, yahoo, and msn, and creates a graphic display of overlapping hits and shows where in the respective SE rankings the hits occur. It also displays links that are unique to each of the engines. Mousing over any of the hits (ie. links) displays a thumbshot of the site.
This morning I stumbled upon another interesting multiple engine search service, resultr This service allows you to create and save your own custom made search engines, by combining from more than 40 pre-selected search engines in 8 categories (News, Blogs, Media, Jobs, Social Info, Reference, Shopping and Local). Unfortunately, there is no way (that I could see) of adding your own favorites - for example Firstgov.gov - to the menu of engines you can select from. Such a feature would make it a far more useful service.
