Yahoo has expanded its search engine to sift through charged-for content, including news from The Wall Street Journal and research from Forrester.

The beta version of Yahoo Search Subscriptions indexes fee-based content and makes it searchable. But finding links to this content via Yahoo doesn't automatically grant users access to it. If they haven't already, users must subscribe with each provider to view the information.
