I'm trying to do a search for all torrent files and pdf files related to "secrets of the javascript ninja".
I can do them individually as shown:
"secrets of the javascript ninja" filetype:pdf (~6560 results)
"secrets of the javascript ninja" filetype:torrent (~146 results)
But how do we concatenate the results? In essense, I would like Google to display the union of the above two searches.
I've tried "secrets of the javascript ninja" filetype:(torrent or pdf) but it doesn't seem to be working. Is there a way to do union searches on Google?
