Hey Wholi,
The www.amazon.de page seems to be using Quirks for the Document Mode. You can manually load the page using Internet Explorer 10, Internet Explorer 9, etc. by following the steps below:
- Open the page in question in the desktop version of Internet Explorer
- Press F12 on your keyboard
- Click Document Mode:
- Click Internet Explorer 10 standards
The page will then refresh and you'll see the search bar displayed next to the drop down.
Hope that helps, look forward to hearing back from you.
Steven
