Wolfram Alpha is not a search engine. It is a computational knowledge engine! It answers questions and computations using Wolfram Alpha's internal knowledge base. This knowledge base is based on many different sources, combined and curated by the Wolfram Alpha team.
It is great for finding "just the facts" and it is meant for use in kindergarten to graduate school and beyond. For example, try typing in "Jupiter" or "Atlantic Ocean". It gives you scientifically accurate, up-to-the-minute information without surfing, opinions or ads.
