Considering the limited data used, it's very good and makes search easier.
5 search suggestions is good. Official sites can be added as a 1st or 2nd item, but could not count towards the total.
I found myself typing exactly 3 characters and waiting for it to suggest something  (4 is an weird number).
UI wise, a box below the input works fine and it's what people expect.
The speed is great.
Zero-click in the search box suggestions? Might be a bit too much.
