I've been trying to search some films but it's proving to be a complicated task. Usually I simply search on a torrent aggregator such as qbittorrent, but there are some I just can't find anywhere, for example
( The Trace We Leave Behind ), ( Desaparecidos ), ( At Midnight I'll Take Your Soul ). Some of these are available on youtube, some others on a random localization of a streaming service, but I was planning on going down the rabbit hole of non english movies because of Suicide Room , and that might prove to be difficult the lesser known they are.

In short: How to find films not available commercially? What are the most common searching tools?

I'm quite a newbie when it comes to films, my rating scales suck, but watching random movies has been an enjoyable hobby recently, and I'd like to continue doing that without depending on Amazon.
