If you are interested in seeing the differences in the results of a Google search and of a Bing search you can use this site from Black Dog, a German web optimization company. Just put your search terms in the top (English) box. You will get a side-by-side comparison of Google and Bing.
You might find it interesting that more often than not, where your search can best be answered by a Wikipedia article, that article will be listed as the top relevant result. Try "quantitative easing" or "double jeopardy" or "district of columbia gun ban."
