Did not Hit Enter and Google is Showing result

I just experienced an amazing change in Google. I think its the new change by Google.

I just type my query and got the results, even I did not hit enter. Also, when I remove my query with backspaces then a blank page is showing.

Example: I just type my query and Google show me results, I did not hit enter and without hit enter, I got my results.

I think its the one of great change in Google algorithm and it may be related to Google Instant.

Update: Google Instant Results: Start typing and results appear right before your eyes. Until now, you had to type a full search term, hit return, and hope for the right results. Now results appear instantly as you type, helping you see where you’re headed, every step of the way.
