While writing a paper yesterday this strange thing happened to me. I was writing it in Word, and wasn't satisfied with the repeated usage of the word "release" in the last few sentences. So, I've decided to open up Google and started to enter the search phrase "synonyms for release". Haven't even finished the word synonym, google autocompleted my search to "synonyms for release".
How could it know that I wanted to look for that exact word? Was it just a coincidence? Does Google have access to some information that could somehow possibly give away what I intended to search? What could have been the reason for it selecting "release" as its first autocomplete?
