Metasearch engines, also known as meta search engines or search aggregators, are search engines that send user queries to several other search engines and then collect and present the results in a unified way. They do not maintain their own databases of web pages. Instead, they act as an intermediary, leveraging the indexing power of multiple existing search engines. When a user enters a query, a metasearch engine simultaneously submits that query to several individual search engines like Google, Bing, or DuckDuckGo. It then gathers the results returned by each of these engines, often deduplicates them to avoid showing the same link multiple times, and ranks them according to its own algorithm. This approach can offer a broader range of results than a single search engine might provide, potentially uncovering information that might be missed otherwise. Some metasearch engines also offer advanced filtering options, allowing users to refine their searches across the aggregated results. Examples of metasearch engines include Dogpile, Metacrawler, and Startpage.
