I had a small media library for myself, and wanted to automate it a bit more, so implemented arr stack (prowlarr, radarr, lidarr), it seems to work but I'm not sure how to pick indexers. I have no experience with it, and I initially just picked a public one, but it barely ever seems to download something.

I'm a bit confused about it, should i just pick as many as I can? Or join a private one? But no idea where to start there.

Any advice or push in the right direction would be appreciated.
