What is the Hummingbird update?

The "Hummingbird" update was the first major update to Google's search algorithm since the 2010 "Caffeine" search architecture upgrade, but even that was limited primarily to improving the indexing of information rather than sorting through information.

Google released the Hummingbird Update to provide a more conversational, human search experience.Hummingbird uses natural language processing that includes semantic indexing, synonyms, and other features to interpret queries and produce results.

Google Hummingbird algorithm update is all about improving results for "conversational search", instead of just looking for key words it helps user search specific questions.This concept is called semantic search. The Hummingbird approach should be inspirational to anyone managing and planning content.
