Google has a special search feature that allows use of advanced search operator filetype: to search for contents of certain file format. This functionality can be used to search for torrent files for BitTorrent network.

In Google search bar, type:

filetype:torrent movie

Replace ‘movie’ with the keywords or terms that you want to search for torrents. If you want to search for torrents related to Jessica Alba, replace ‘movie’ with ‘Jessica Alba’.

But, you won’t find many torrents with Google though. Obviously Google won’t leads you to contents that infringe copyrights in order not to attract lawsuits.
