Search Engines

I don't know a whole lot about search engines but my sister is going to come over this week and put a couple more on my computer. I am having quite a time with the only one I have now. I think she said she has 3 she uses all the time. It will be great to have another search engine to depend on when this one gives me problems. I hope to learn more about computers all the time too. They are sure a good way to pass the time of day on a bad weather day.
