But That’s What I Wanted!
Sometimes you actually want to get results for a search query you know
is going to cause problems, such as filetype:pdf. It seems reasonable that
this query would return every PDF file that Google has crawled, but it
simply doesn’t. In cases like this, you just need to be a bit creative. To get
a list of every PDF file, try a query like filetype:pdf pdf. This query asks
Google to return every PDF file that contains the word pdf’—but
remember, Google automatically searches the URL for your search term,
so every file ending in .PDF will have PDF in the URL.
