What is the function of a meta search or search aggregator?

The function of a meta search or search aggregator is to search multiple search engines simultaneously. This type of tool enables users to input a query once and receive results from various search engines, consolidating the information and presenting it in a single set of results. This is particularly useful for users looking for a comprehensive overview of available information across different platforms, as it saves time and increases the breadth of search results.

Using a search aggregator can significantly enhance the efficiency of the search process by eliminating the need to visit and search through multiple websites manually. It taps into the strengths of various search engines, allowing users to leverage diverse algorithms and indexing methods to find relevant information more effectively.
