If you want to search more than one search engine at the same time,
this category is for you. One request is simultaneously conducted in several
search engines. Beware, though, of limitations. The search may be slower,
and the search cannot be customized to a specific search engine. For "quick"
results, this can be helpful. Also good for distinctive words or phrases.
MetaCrawler
(http://www.metacrawler.com/index.html): Queries seven search engines
simultaneously: Lycos, WebCrawler, Excite, Alta Vista, Yahoo, HotBot and
Galaxy. Results are sorted by relevance or by location. Advanced
searching syntax available.
SavvySearch

meta-search tool that targets more than just comprehensive Web
navigators. Search, with experimental interface, Web indexes, Web
directories, Usenet News, people, software, reference, entertainment,
technical reports. Search each category separately. Has no commercial
