The new wikia.com page is not using the wiki engine, so that's one reason it doesn't show the search bar. Also global search never worked well, so they may have effectively killed it.

People are also most likely running into the flaky behavior of JS and the global nav search bar. I've seen several situations where it hid itself, but never reappeared without a manual refresh. The global nav is lame.
