Hummingbird was essentially an entirely revamped version of Google’s search algorithm, not just a patch or minor update.
Hummingbird brought the concept of semantics, or meaning to search results. Semantic search is the concept of improving search results by focusing on user intent and how the subject of a search relates to other information in a wider sense, or its contextual relevance. Essentially, semantic search focuses on determining what a user really means, rather than a string of keywords, and then serving relevant results.
