Google translate & search engine : how it works

I recently found out the way Google search and traduction works. In fact , i'm studying Data Mining and it explains of course how search engines works. Although, the Google's algorithms still unrevealed ( otherwise it wouldn't be the leading search engine in the world ! ). I found two videos about Google search engine and Google translate , where the concept is explained by Matt Cuts ( Matt Cuts is a software engineer who joined google in 2000 and he is the head of Google's Webspam team i will share a link to his blog in the bottom of the article ).
I wont lie, i was always curious about Google translate algorithm and what frustrated me was how can Google Translate use grammar rules !!! I will let you discover ( if you don't know it ofc ) the Google's secret :)
all the best,
