What Are Multi-Search Engines?
A multi-search engine combines many search engines into one unified search engine. It is a fast and comprehensive way of casting a wide net on the Word Wide Web. There are thousands of search engines on the Internet. Although some are quite good, none of them is comprehensive. Some may use a small database to create your result set, some may not be updated regularly, and still others may be quite slow. Thus, you may need to use several search engines to ensure an all-inclusive search result. Multi-Search engines may use from as few as ten to as many as thousands of search engines.
