Modern search engines try to guess your actual question from just a single word.

When you search, you do not just get a list of links. The system actively guesses what you actually mean, even if you only type one word. It does this to make search feel fast. But it also means the system is constantly building a model of your intent. It limits what you see to just a few highly targeted results. This makes it feel like the machine is looking back at you and reading your mind.
