Wolfram Alpha is known to be a “Computational Search Engine”.
So what does it mean?
It basically gives a result based on the question or calculation entered in the search box. Like other search engines, Wolfram|Alpha uses a search algorithm with a growing collection of data to be presented to users. Wolfram|Alpha, developed by Wolfram Research, “is an online service that answers factual queries directly by computing the answer from structured data, rather than providing a list of documents or webpages that might contain the answers as a search engine might”. The only thing that makes Wolfram|Alpha a unique search engine is its ability to compute mathematical equations.
