Meta Search Engines -

Meta search software sits on your computer and enables you to search through many internet search engines simultaneously and to view and use the results. You can browse through the results on your computer and click those pages that you want to visit.

Meta search engines do not create their own database but make use of the database of other search engines. They quickly process the user's search by invoking several individual search engines at once and return the results compiled into a convenient format.
