Search the web for a file with a particular filename?

Question

I'm looking for a search engine that will let me query sites with a particular filename. That is, I'm looking for sites that host a file with a particular filename.

I tried the mainstream search engines (Google, Bing) and also Archive.org, to no avail.

It's possible I just didn't find the right query syntax.

Anyone know how to do this?

Answer 1

I'd use Google with a combination of inurl: and filetype: operators, e.g.

filetype:pdf inurl:example.pdf

Some false positives are possible, but usually not likely.
