Google 101

During Google 101 I learned that you can put .gov, .edu, ~,-, and + in the search box to make your search easier and able to find more relevant information with them as well.  I also did not know about the search tools on the left hand side of the Google page when you typed in your search string and hit search.  I've realized that these tips will help me out quite a bit with looking for my online resources.  If I can't find what I need the first time I will use the search tools and tricks right away instead of going around looking on a bunch of other different websites.  I feel as though this will help me out with my research with whatever topic it is that I need to find more information about.
