Search engines are programs that search documents for specified keywords and returns a list of the documents where the keywords were found. Web search engines, like Google, Bing and Yahoo!, enable users to search for documents on the Internet.
Typically, web search engines work by sending out a spider to fetch as many documents as possible. Another program, called an indexer, then reads these documents and creates an index based on the words contained in each document. Each search engine uses a proprietary algorithm to create its indices such that, ideally, only meaningful results are returned for each query.
Meta search engines are search engine tools that pass queries on to many other search engines and/or directories and then summarize all the results in one handy interface.
A search directory is a website in which links to information are organized by subject, and in alphabetical order, to make it easier for users to find the information they're seeking.
