Search Engine |
A Search engine is a tool for finding information on the Internet. Most search engines consist of the following main components:
1. Spider
2. Indexer
3. Database
4. Search software
5. Web interface
Documents found by the spider are processed by the indexer and stored in a database. From the database the search software extracts documents based on parameters entered by the user. Examples of search engines include Google MSN and Yahoo!. Directories like Yahoo! and ODP are often referred to as search engines although they are not.
