There really is a way to balance these two things: you don't censor outright, but you just don't rank it highly. So it's not easy to find, but the moment someone searches about something, or spends more and more time narrowing down results in search of something that matches a piece of data - if they really want to find data pertaining to their query - then in the index they can.
It might result in a resources problem (or storage and computing power), but theoretically it could even exhaustively apply to spam. Even spam would be indexed in a radical free speech database, but with good algorithms it'll just take longer to find because a very small (almost zero) people in the world algorithmically denote it as content of worth.
