Played a bit today with Google Trends to see whether it might be useful for education research. Conclusion is ... perhaps. For instance, this search for "Common Core" amongst the 50 states from 2010-present yielded potentially interesting data.
The key, obviously, is to have very clear language that would not be used for other purposes. "Common Core" is probably a good example of a term that would work but "technology leadership" wouldn't work.
