Google Introduce a new change in it's Algorithm "Hummingbird"

This recent change in google's algorithm will answer your basic queries in the form of question directly.

Other things announced in the surprising event(at Garage) include a tweak to Google’s Knowledge Graph to allow it to handle comparison questions (“Which is better for me — olive oil or butter?”)

The main focus, and something that went repeated many a time, was that the new algorithm allows Google to more quickly parse full questions (as opposed to parsing searches word-by-word), and to identify and rank answers to those questions from the content they’ve indexed.
