How I searched for search engines...

World Wide Web-based search engines drive me crazy. With UC Davis being a place where everybody is researching something all the time, a good search engine seems like it would be every student's best friend. However, it seems like there are hundreds of engines out there, each claiming it is bigger, faster and more accurate than the rest. How am I, one little student with no extra time on my hands, supposed to figure out which one I should use?
