Search Engine History

The concept of Meta-Search Engine came into existence in which a single interface provided search result that was generated by multiple search engines rather than a single Search Engine Algorithm. Daniel Dreilinger at Colorado State University developed SearchSavvy which let users searched up to 20 different search engines at one and a number of directories.

MetaCrawler improved on accuracy of SearchSavvy with the addition of its own search syntax and behind the scenes, matching its syntax to that of the search engines it was probing. MetaCrawler searched through six search engines, yet while providing better results, still could not match those achieved by searching each engine individually.
