Microsoft has unveiled the full-release version of its search engine, which will compete against Web search leader Google. According to Reuters, the launch of MSN Search comes three months after the release of an initial beta version. Microsoft had been using Yahoo unit Inktomi to power its search services, but will no longer do so with the full release of its search engine, which uses Microsoft's own technology to sift through the Web.

The software maker says it has also revamped its MSN.com Web portal to make its search engine more prominent, and also tweaked the site's content and advertising to remove clutter.
