Metacrawlers and Metasearch Engines

Unlike search engines, metacrawlers don’t crawl the web themselves to build listings. Instead, they allow searches to be sent to several search engines all at once. The results are then blended together onto one page. Below are some of the major metacrawlers. Also see the Search Toolbars & Utilities page for metacrawler-style software that you can run from your desktop.

Click the trash can icon, and the listing goes away. It’s a great way to prune your results — even better would have been if everything trashed brought up something new to look at.
