To search for articles in the encyclopedia, simply enter the topic you want to search for in the search box. To see all the pages related to a topic (I'll use the ancient Greeks as an example), type in the text box: Ancient Greece, and click Search. Another way to get a listing of articles on the topic would be to type Category:Ancient Greece. To go to the portal for the Ancient Greeks, you would type: Portal:Ancient Greece. If you knew the name of a photo, but didn't want to go to the page it is on to see it, you could type it in and go straight to it: Image:Caerulea3 crop.jpg, by clicking Go. The namespace prefixes are: Category:, Portal:, Image:, User:, Talk:, Wikipedia:, Help:, and Template:. When using prefixes, you must know or guess the exact name of the page - the search will not list similar pages. This method is most useful for going directly to a page you already know about. We'll cover other ways of searching namespaces in upcoming tips.
