AECC Global, an India-based student recruitment agency, has launched an online course search service, according to this article. "The platform features tens of thousands of courses from AECC university partners in key destination markets including Australia, UK, Canada, US, New Zealand and Ireland." There's no link to the service in the article, but this might be it - but if you do a search, you can't actually search for subjects, only a faceted search for full programs., or a 'career outcomes' search which again leads only to full programs. Here's a video. A service like this may be useful to someone planning to spend thousands of dollars (or lakhs of rupees) and years of commitment. But for everyone else, we need something much more fine-grained.
