Business search engine organizes and saves results

find.com business search engine clusters search results into folders, optionally organized by topic, format, web site address or internet source/search engine. This is in beta form but seems to have full functionality. It's free now...and has the characteristics of the Northern Light search engine, before it became a pay service. Much like Copernic, it saves your search categories and results in folders, listed in a pane, in the left column.
