Search the Web¶

Search Engines

A web search engine bases on an index, which are created by humans and/or computer generated; only indexed websites will be found.
If you are searching for local informations try first to use local search engines. e.g. if you are looking for something in Germany try a german search engine like metager.de

so many searchengines:
www.powerset.com
www.ithaki.net

with visualition: grokker.com

and www.scroogle.org/cgi-bin/scraper.htm

Difference between search engine and meta search engine (e.g. www.xooda.com)
