Google Advanced Search Brings Back the Black Bar

I checked Google's advanced search page and noticed something strange: after clicking the "advanced search" button at the bottom of the page, Google sent me to a search results page that included the old black bar navigation menu.

One of the culprits is the "as_qdr" parameter that somehow triggers the old interface. This URL sends you to the old Google interface: https://www.google.com/webhp?as_qdr=all. You can bookmark it if you miss the black bar.

Another way to bring back the black bar is to use the "noj" parameter like this: https://www.google.com/?noj=1.
