In a blog released recently by Google Product Manager, Satyajeet Salgar, we've been told that Google has now gotten even smarter - opening up the ability to recognize and process much more complex question than ever before.
Splitting up terms into different categories, a question such as 'Who was the US President when the Angels won the World Series' will be recognized in sections which include presidents, countries, baseball teams and world series winners by year. The example on this blog explains that Google will then search the two terms: 'presidents of the US' and 'year the Angels won the world series', placing them together to tell you that George W. Bush was in power.
This isn't limited to desktop searches either, you can now speak into the Google app on your smartphone with it working exactly the same way. There are some deeper explanations and more examples on the blog, head on over if you're interested.
