A program that looks through documents for specific keywords and then provides a list of the ones that contain those words is known as a search engine. Even though a search engine refers to a broad group of programs, the term is frequently used to describe methods allowing users to locate documents on the Internet.

When people use the phrase 'search engine' regarding the Internet, they are normally talking about the search forms that sift through databases comprised of HTML documents that were originally accumulated by a robot. Essentially there are only three kinds of search engines: Those powered by robots, those powered by information provided by human beings and those that are a combination of the two.

A Crawler-based search engine is able to quickly develop a list of related sites because of automated software agents called crawlers. Crawlers are able to visit different sites, read the content and meta tags, and also to follow all links listed quicker than a human being could.

The crawler sends back all the data to a centralized reserve where the information gets indexed. The crawler goes back to the sites from time to time in order to confirm if any information has changed. The occurrence of this is established by those who administer the search engine.

Another category of search engines are the ones that are powered by humans who submit information. This information is then indexed, ensuring that only information that is specifically put forward is entered into the index. In either case, it's this index that the search engine has created that you are consulting when you try to find information through a search engine query.

This suggests that you're not really looking on the Internet. These databases contain an enormous amount of information that is gathered, stored and then searched. This accounts for receiving dead links when performing a search using a commercial search engine. The results of the search are established by an index. If the index hasn't been brought up to date since the web page became useless, the search engine still recognizes the page as an active link, even though it is no longer valid. It will stay like this until the index gets updated.
