The easiest way to start off using Scout is to show up to the homepage and type a keyword or phrase into the search box.  It'll search over everything all at once. You can either create an alert right away by hitting the "Create Alert" button, or you can first narrow and filter the search down to what you're really looking for. Whatever search you see in front of you when you hit the "Create Alert" button is what we'll notify you about new results for.
