This constructs the search vector for all new future members, but can we run it in this migration for all existing members as well?

But is this a use case?
I would rather put that in an own low priority issue due to priorisation if that's fine?

Yeah, I think if we all just reset our database we should be fine as well. No need to create an issue. I was just confused that I could not find all members in my database :D
