I was reading about search engines and i have seen that google for example is crawling and expending it's indexes by finding new links inside of the current websites he is scanning at the time. So my question is, how does Tor do that? How can you find websites that doesn't have any links pointing to it? How does Tor locates websites that are made especially to be hidden?
If you have any sources or even better a simple detailed answer for me it would be truly great
