This is customized for the site to 'power their own search'. The query sent to Google is based on the keyword but also on the article type (in this example) and then the xml that is returned is post-processed to have a custom render per article type.
Since we had all the data the results from Google were compared to a local search I setup in Sphinx (http://sphinxsearch.com/) and the Google results were more relevant and it was a lot cheaper to deploy.
