Website search interfaces
Of course, there’s the classic search results page with its familiar green blue and grey colours. But famous search result pages have become much more than that. They often include cards with useful snippets of information. Maybe you found what you needed instantly?
But there are also other, interesting interfaces for searching. One that has stood out for me several times (in the graphical user interface rather than the actual search index) has been the global search on observable.com. It seems to have several different UIs depending on the context, but to be clear, I made a screen cast of it.
