I had to research the the windows live search engine. I really liked it. I was able to find things for Lou Gehrigs disease that I wasn't able to find just using google and yahoo.

Windows live was able to pull up pages that had a lot of useful information. They also give you a good discription of the page before you even click on the link. Unlike google and yahoo that gives you everything that has even one word of what you are looking for, so you get a lot of extra stuff that you don't need.

The one down side to this is that you have to know exactly what you are looking for and put that in, otherwise you will get anything and everything
