This data is almost as if Google dropped its full data down on a silver platter for you to dig into. Why? Wikipedia has the unique privilege of being very much like a search engine (in that most people visit the site and search for something they'd like to learn more about). It also has the added privilege of high -- often #1 rankings -- on Google. When you take a #1 term's view-count for a given day you can easily assume that the term gets searched around that many times on Google for that same day.
