Seek is pretty great.
Might you be considering the option to seek ‘non-linear’ content, nested stacks perhaps? That is, to allow for seeking more exiting layouts as well, such as a card deck, for example, wherein each card is separately identifiable as a potential search result (other cards becoming invisible, visible ones reshuffling into order)?
Your seek sample of superheroes is nice, but I can’t see a way to have a columnar layout for them. Unless I am missing something, for now, each search target must be above or below one another.
Thank You.
