Yahoo search has introduced YQ. To taste YQ you need to have Firefox and installed Greasemonkey.
What is YQ?
Ans:- It gives contextual search in Firefox. After installing Greasemonkey restart firefox and then right click this link and choose Install User Script or View user script source and click install. Thats it.
It is better way to search topics because you don’t have to type any thing and get best result quality but small in quantity. Till its development is under beta, so we can expect more later out of that kind of contextual searching.
