Yahoo has rolled out a nifty new tool that lets you use content you're viewing as the basis of a search query, providing results that are difficult to get otherwise without using advanced search commands.Several interesting points:
The new tool, called simply Y!Q, lets you use all or part of a web page you're viewing as the source of a search query. Simply highlight relevant portions of text on the page and run a "related search," and Y!Q analyzes the page, extracts the most relevant concepts and uses those as inputs.
If you're a Firefox user, Yahoo offers a Y!Q plugin for the search bar.
Y!Q is part of Yahoo Next, the company's playground for showcasing new technology which is similar to Google Labs.
Yahoo release Y!Q in less than polished form so that it could get feedback from users to help improve the tool.
