Search Engines - Get Information On The World Wide Web
A program that searches the documents for specified keywords and returns a list of the documents where the keywords were found is called a search engine. Although search engine is really a general class of programs, the phrase is often used to specifically describe some systems that enable users to search for documents on the World Wide Web.
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.
When you use a search engine to look for something, you are not actually going out on the internet and looking at existing web pages. Search engines use large databases of information that are collected, indexed and periodically updated. These databases are looked through when you do a search to find relevant information. This is why you can sometimes get dead links in a search if that link has not had its index and information updated since the link went bad.
