I'm honestly confused. Are you complaining about "joinpeertube.org" or the typical Peertube instance? If the former ... why would you want it to have any search capability? It's not a video host. If the latter (e.g. https://peer.tube/), the search is not at all hard to find.

Completely agree. I actually think Sepia search is quite good. It's what peer tube desperately needs and it's so much better than the individual search features on all the different instances which are a complete mess. So I don't understand why it's pulled out into a separate brand and separate domain.
