If you had issues with search results then the problem is your indexers, Sonarr queries the sources you give it, if you give it bad sources then it’s going to have bad results.

I use Sonarr and Lidarr with private trackers and usenet where usenet is the preferred download source. I also use Jackett to combine the trackers so I can make one query from Sonarr to multiple trackers. Previously, for the longest time, going back to 2007, I used a torrent client with an RSS feed to download new TV show releases. It worked, but Sonarr provides far more granularity. And it is wife friendly, she can easily go on and add a show by herself. I don’t know of anything that works better than Sonarr, so OP… what would we have been using instead of it?
