How is a relay determining it? I think I'll just leave this to the devs lol cos I won't understand the answer maybe lolol.

But let's say I make a post about a particular plugin or vst for music production. But I haven't mentioned the words 'music production' or whatever other words, but I want it on that relay. How would a client determine this, it couldn't possibly have all the possible words and brand names associated with a topic. And what about let's say I was also mentioning it was for the audio of a film. Would it then determine to post instead to a film relay? Or post to both?

I have no idea. Lol, I assume there are ways:) lol
