Search engines allow you to search for web pages that match certain criteria. Each search engine has its strengths and weaknesses. If your search is not successful with one search engine, try another one.
Meta search engines search other search engines. They are only useful if your search is very narrow and there are only very few matching pages.
In recent years Google, www.google.com, has become the most acclaimed search engine.
The Search Engine Watch website, searchenginewatch.com, provides interesting background information on search engines, how they work, how to use them, and how they compare.
The Search Engine Colossus website, www.searchenginecolossus.com, lists 1400 search engines from 135 countries around the world.
Another index of search engines, meta search engines and other Internet search tools is Freeality Internet Search, www.freeality.com.
SearchEngines.com, www.searchengines.com, also maintains an extensive list of search engines and directories.
