Has anyone seen this before?
Search within search. Pretty cool feature. Anyone know how to add this?
Update: The feature is about a week old, according to this Google post, which explains it’s fully automated: “This feature will now occur when we detect a high probability that a user wants more refined search results within a specific site. Like the rest of our snippets, the sites that display the site search box are chosen algorithmically based on metrics that measure how useful the search box is to users.” Thanks Amanda for solving the mystery!
