Which is the oldest search engine in the internet?

At 19tijn Koster, a software developer at Nexor, created some programs to manage and index the emerging Web. A search engine is a software system designed to perform searches on the web. They systematically search the World Wide Web for specific information specified in a textual web search query. Search results are usually presented in a result line, often referred to as search engine results pages (SERP).

The information can be a combination of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also extract data available in open databases or directories. Unlike web directories, which only maintain human editors, search engines also maintain information in real time by running an algorithm on a web crawler. Any Internet content that cannot be indexed and searched by a web search engine falls under the category of deep web.

Of all the search engines that still survive, WebCrawler is the oldest. Today, it aggregates Google and Yahoo results. Lycos (199) Altavista (199) Excite (199) Yahoo (199) Dogpile (199) Ask Jeeves (199). Due to the limited resources available on the platform on which it was running, its indexing and therefore the search were limited to the titles and headings found on the web pages found by the crawler.

Smartphones were the catalyst for an unfettered search and browsing experience, putting a small computer in everyone's pocket. Google arrived relatively late in the search group, based on several ideas existing in 1996 and launched in late 1997.Other search engines were starting to suffer from spam and relevance issues, which would become Google's golden bullet and the secret to its success. The same year that Bing was launched, Microsoft signed an agreement with its closest rival in search engines, to boost Yahoo search results. Some have removed their public search engine and are marketing business-only editions, such as Northern Light.

Beyond simple keyword searches, search engines offer their own command-driven operators or GUI and search parameters to refine search results. Perhaps if Ask continued to develop their technology, today they would be leaders in voice search, where question-based searches are key. Most search engines support the use of the Boolean operators AND, OR, and NOT to help end users refine the search query. Therefore, it was the first WWW resource discovery tool that combined the three essential characteristics of a web search engine (crawling, indexing and searching) as described below.

The following month, Infoseek took over Excite as the default search engine on Microsoft's WebTV and Infoseek Express, a free software website, was launched. Concerns about search privacy ceased to become a paranoid topic for technology experts and into general awareness. In 1990, Alan created Archie, an index (or files) of computer files stored on anonymous FTP websites on a given computer network (“Archie” instead of “Files” conforms to the name's length parameters, so it became the name of the first search engine). Archie was quickly followed by Veronica, a service from System Computing Services at the University of Nevada that tried to provide Archie-style searches for plain text files.
