While searching through Google, you may have seen a slightly new look for specific search results. That’s only because, Google has launched a new way for users to orchestrate a site search on a website within the search results through the sitelinks search box.

It seems Google is testing this to notice the level of interaction with their users, because the results aren’t coming as perfect as they ought to be.
