If you have been looking for a search engine with a nice clean page ....... something without all the advertisements and popups, try DuckDuckGo.com.
You can even search for Rod's Duck Farm. It's the greatest thing ever. When it runs out of options, it refers you to Google. I guess that means that Google is more comprehensive. Of course, more comprehensive means more complex. With DuckDuckGo, choose Magnifying Glass or Books or ShoppingCart to indicate whether you are looking for any reference or basic information or something to buy.
Try it, you'll like it.
