Summarize the following:
It's the white bar that likely has text in it at the top of the browser page. Sometimes Facebook users who won't appear in an internal search will appear in a Google search. Replace the word "First" with your user's first name and "Last" with their last name. For example, you might type site:facebook.com "Old MacDonald". This will search for your selected user in the context of Facebook pages. Doing so will open the user's profile in limited view; in most cases, you'll be able to see their profile image and name. You can also use an image search to confirm that the profile for which you're searching matches a result. If your selected user has a profile that appears in search engines, you'll see their profile picture, their name, and any other information that they have chosen to make public.
Click your browser's URL bar. Type site:facebook.com "First Last" into the URL bar. Press Return (Mac) or Enter (PC). Click a search result. Review your selected search item.
