Are you talking an AdSense Search box or actually displaying AdSense ads on the page? I don't believe you need any content for an AdSense search, but you'll need more if you're going to display ads on the results page.
AdSense Search:
[google.com...]
You could make a zero results page with a "Didn't find what you are looking for? Here are quick links to our most popular sections of ABC Widgets" with some links and descriptions, which would give the page some content in the eyes of AdSense.
