I found an interesting PDF with my last Google research, via a direct link to it ( Google result was like "http://example.com/somefolder/interesting.pdf").
I would like to put the pdf in context, that is to say find a webpage linking to it. How can I find it? I tried to google http://example.com/somefolder/interesting.pdf, but I got only one result (of course the pdf itself). If I google "example.com/somefolder/interesting.pdf" I get no result.
Does that mean that the original pdf is an "orphan" attachment?
Is there any option in advanced search that I missed? Maybe is there another search engine with this feature?
