Web search engine
web search engine is a software system that is designed to search for information on the World Wide Web . The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a specialist in web pages , images, information and other types of files. Some search engines also mine data available in databases or open directories . Unlike web directories , which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler .Timeline (full list )
