Google recently launched a new labs tool called Google Correlate. Given some data (either via a search term you enter or from data you upload), the system ranks all queries (in what I assume is a subset of the entire space of queries issued to Google) in terms of how well they correlate to the object data.
With this, we might notice that searches for 'margaret thatcher' have a reasonable correlation with 'ronald reagan biography', the most correlated term for 'live labs' is '10 meters is how many feet', 'world cup' with 'copa mondial', 'bayes' with 'lithography', etc.
Perhaps a little less well known, but predating Google Correlate is Eidosearch. This is similar to the above but with the twist that you can define the query in terms of an arbitrary span of a time series. Watch the video:
