There are many sites that utilized Yahoo! Search BOSS and successfully built their own vertical search engines. For the green search engine, the typical example is Truevert. And despite the fact that Truevert search engine is powered by Yahoo!, but it uses its own proprietary, patent-pending technology to select and rank the results it gets from YAHOO! instead of render the generic YAHOO! green results.
Basically, green issues are hot right now. For those who want to search the green stuff for the good of the planet, Truevert has a simple interface that includes search function in addition to the recent green news which are all pulled from the popular green Web sites.
To know more about Truevert, I’ve embedded a visual presentation about this green search engine. Enjoy.
