I have gone through the blog post and bit of code but I am a bit stomped. Can anyone tell what is the flow here?

If I go directly to /search/q=hello, the request will go to server, it will render the HTML on server and send it to client. What happens next? Do they send all the Javascript + client-side templates alongside as well so that further requests are catered on client?

Think I should fiddle around with the sample app.
