Search engine is a software program that lets you search the internet using keywords.
How does a search Engine Work?
The search engine contains two programmed elements: spiders and index. The spiders or crawlers is a search engine robot that searches the internet for the keywords. It is called a spider because it crawls the web continually, examining Web sites and finding and looking for links.
The index: When the spider finds a page, it feeds that data to the index.
