I've searched for ext:PDF
(filetype version) of a probably popular = commercial successful book and got full page (maybe more) of spam links – it's more than 100!
How to deal with a full page of spam links in the google search results, how to get more relevant results?
- Somehow put all (un-relevant) domains into the filter?
- Report all of them – impossible task or must be automated?
- Other options?

If you find information in Google's search results that you believe result from spam, paid links or malware, here's how you can report it:
SPAM - https://www.google.com/webmasters/tools/spamreport
PAID LINKS - https://www.google.com/webmasters/tools/paidlinks?pli=1
MALWARE - http://www.google.com/safebrowsing/report_badware/
BONUS: copy/paste this into the search box and the first result should be valid:
"The Personal MBA: Master the Art of Business" ext:pdf .pdf
not sure if this is actually what you seek: link to pdf
