Thread:Project:Support desk/I see search results page instead of article

I've recently upgraded from MediaWiki 1.22 to 1.23, and I notice now that when I type in a search term, I always see a search results page, even if there is an article that matches the name.
 * Before, if I typed "XYZ" and if there is an article named "XYZ", the system displayed that article right away.
 * Now, I get a results page that says "There is a page named XYZ on this wiki", lists that page and then a bunch of other pages that link to it.

Is there a setting that's changed that I'm not aware of? Can somebody point me in the right direction?

Thanks!
