Using Google Advanced Search allows you to refine a Google Search. Below, I’m going to search for Salem Witch Trials in the section all these words, and I’m going to limit my search to only .edu under site or domain, which means only educational websites. This allows me to look at edu sites, but I still need to evaluate them.
