Even though the search bar is in the global navigation, it is for the local site. So if you used it on minecraft.fandom.com, you wouldn't get results from starwars.fandom.com. The same is true when you search for things on www.fandom.com.

www.fandom.com is a bit of a special case as it is not actually a wiki. Rather, it is Fandom's site for posting things such as commentary and review on movies, games, anime, etc. Because it is not a wiki, it has significantly different features and structure from the wikis that compose the rest of their farm. From what I can tell, the search at www.fandom.com is strictly limited to that site.

If you use the search bar on a wiki, it will take you to Special:Search. If you look around the page, you will see that it offers several additional search criteria you can use. One of these criteria is whether or not to limit your search to the local wiki. Even though this search page supports interwiki searches, it returns specific pages, not wikis as a whole.

On the search page, you may also notice the "Related Wiki" on the right of the page. If you scroll to the bottom of that section, there is a "View More Wikis" link which will take you to a search for wikis based on your search term.
