Example of embedded http://thorrents.com search, and a tribute to Cory Doctorow ;) tnx to @thedod

See it live here.

If you want to embed this (or any other search) in an existing page:

• Remove first and last line and paste this where you want it in the <body/>.
• Change query to whatever you want to search (and maybe change limit).
