How does Google Chrome suggest url completions?

Question

I've learned about Google's (unofficial) suggest API and their search API, which both look really great, but the suggest API doesn't actually suggest navigational completions. On the other hand, in Google Chrome if you start to type for example "apple", it will suggest "www.apple.com/trailers".

I know it searches your browsing history, but I've never been to that page so it's not getting it locally.

Is this another unofficial secret API?

Answer 1

Click Options, Under the Hood and you can see which services it searches for it's navigational selections. It sounds like it's combining history and search suggestions for you.

Answer 2

It doesn't. It can't work that out...
