Still can't find what your looking for? Have you tried Amazon's A9 search portal yet?
The site boasts a "Beta" status but is quite useable. The typical listing of hits is provided as well as related image thumbnails akin to Goggle's image search crawl. Sidebar tabs link your search term directly to other criteri like a Wiki crawl, movie search etchttp://gisuser.zoto.com. See http://a9.com
