Custom Search Engine ::: Google or Yahoo! ?

Well, If I come to the point straightly I must tell you that Yahoo!
looks good but Google works better. You can add a site in Yahoo!’s
personal search engine. But you can add as many web pages or sites you
like in Google CSE. You can build a search engine that can be
collaborated by volunteers.There’s options like Subscription Links and
AdSense integration.You display results on your own web page or on a
google hosted page. These features are not in Yahoo!. Google gives you
total control!
