Meta search engines are facilities that list the top results from a number of search engines. Listed below are well-known, well-used or long-established meta search services.

Dogpile
Popular metasearch site that sends a search to a customisable list of search engines, directories and specialty search sites, then displays results from each search engine individually. Owned by Go2Net, which also owns MetaCrawler.

Ixquick
Meta search engine that ranks results based on the number of "top 10" rankings a site receives from the various search engines.

MetaCrawler
One of the oldest meta search services, MetaCrawler began in July 1995 at the University of Washington. MetaCrawler was purchased by Go2Net, an online content provider, in Feb. 97. The commercial backing has helped improve the responsiveness of the service. MetaCrawler now also powers searches at the Go2Net portal site.

QuickBrowse
Want to get multiple pages of results from a search engine combined into one single page? QB-Search will quickly join up to 200 pages of listings from major search engines. It's a simple, helpful tool that you'll no doubt need at some point. Another powerful offering is QB-Masterpage, which will combine URLs that you select into a single page for quick browsing. Both are available from QuickBrowse.

Search.com
Search.com is a meta search engine operated by Cnet. It offers both web-wide search and a wide variety of specialty search options. Search.com uses technology from SavvySearch, which was acquired by Cnet in October 1999. The SavvySearch site itself no longer operates. SavvySearch was one of the older metasearch services, around since May 1995 and formerly based at Colorado State University.

Inference Find
An alternative to typical metacrawlers, Inference lists results by subject, rather than by search engine or in one giant list. For example, a search for "Uma Thurman" groups results into "Uma Thurman" and "Pulp Fiction," among other categories. The service began in May 1995, moving to its present domain in Oct. 1996.

ProFusion
Customisable, with broken link detection and search tracking available. Formerly based at the University of Kansas, the site was purchased by search company Intelliseek in April 2000.
