A test search site from Google launched in late 2006. Designed for trying out new search engine features, SearchMash (www.searchmash.com) produces the standard results pages along with a tabbed menu for images, blogs, videos and Wikipedia. Clicking any of the menu options displays image thumbnails, text excerpts or a small video window, all of which can link to the full content on the target site. A Feedback menu helps Google learn how effective each search was, should the user wish to answer the short list of yes/no questions. See Google.
