Does briefly showing advanced search options on page load increase their use?

Early last year, Jakob Nielsen complained that:

In general, we almost never see people use advanced search. And when they do, they typically use it incorrectly — partly because they use it so rarely that they never really learn how it works.

Since then, I've noticed the BBC using a nifty technique. They display all the advanced search options on page load, and hide them again a second or two later.

It's a little like advertising your advanced search. You can see it best on their Food site.

Has anyone tried this technique, or better yet, have any evidence that it has an impact on search behaviours?
