When you need to search the internet for something, Google and Yahoo! are the two places you will ever need to go. But why visit Yahoo! and Google separately to search for the same query when you can do so at the same time.
Try Releton. Releton returns results for your query from both Google and Yahoo! search engines. You can choose how much significance you want to give to the two search engines using the slider on the website. By default the silder is 50-50, giving equal importance to both engines.
Try it & save time.
