Amazon Search Change?

I used to be able to search for a specific Kindle book on my iPad by going to the Amazon home page and choosing Kindle Store in the drop-down menu. Then I’d see a list of Kindle books related to my search.

Now I only see three rows: Sponsored Products related to this search, Most-viewed products related to your recent searches, and Your Browsing History.

Has Amazon changed the way search results are presented? How can I change it back?
