Yahoo: No. 1 for PDF-file

I am no. 1 in Google with my seach term "kennzeichenhalter" (license
plate holder) for many month.
In Yahoo there are a lot of PDF-files on the first places.
How is this possible? Can PDF-files be better optimized for search
engines than html?

There is more to a ranking than what you optimize for on your own page.
And apparently Yahoo doesn't mind PDF files.
