Forum:How do you have multiple names for an article?

The title might be a bit misleading but I didn't know how to word it better. Anyway, I noticed that in the search bar if you type in something relating an article, even if it's not the name, it takes you right to it (for example 11th September 2001, September 11, September 11 attacks, 9-11 all take you to 9/11). I just wanted to know how do you give your articles multiple names like that.--WeakMindedSkeptic (talk) 11:58, 2 May 2016 (UTC)
 * You can create a redirect to the actual article title, simply by creating a page with #REDIRECT PAGENAME as its content (replace PAGENAME with the appropriate title).--JorisEnter (talk) 11:59, 2 May 2016 (UTC)
