Interesting project.  Sounds like AJAX technique is used to capture and transmit every keystroke.   I expect the result (automatic suggested words)  to be shown down the search box while you are typing.  I tested your link, but only got a download.  Do I miss something?

You'd write some javascript to query the service with every keystroke, e.g.
http://id.loc.gov/authorities/suggest/?q=Hi replies with subjects beginning with "hi*"  It looks like covo.js supports LCSH, so you could look into that.
