More than just words. I've found LLMs immensely helpful for searching through the latent space or essence of quotes/books/movies/memes. I can ask things like "whats that book/movie set in X where Y happens" or "whats that quote by a P which goes something like Q" in my own paraphrased way and with a little prodding, expect the answer. You'd have no luck with traditional search engines unless someone has previously asked a similar question.
