A new and improved Internet search tool is set to debut, but experts say it won't topple Google from its leadership position.

WolframAlpha is a powerful service that can actually answer questions from a repository of verified information – returning complete answers to queries rather then simply pointing users to the millions of Web pages that may contain a similar reference.
The service was created by Stephen Wolfram, a former child prodigy who presented his first physics paper at the age of 15 and developed the maths-formula software Mathematica.
The knowledge base for WolframAlpha is being built up by more than 100 employees at Wolfram Research and is all verified before being made available to the search engine.
Users type in their questions and the system should return the answer – not a list of Web sites.
