Search Engine History
source : http://blogoscoped.com/history/
- 1957-1990: Previously on the Internet : In the late 80s, the number of Internet hosts breaks 100,000, and people are starting to get lost. In 1990, before the days of the World Wide Web, McGill University student Alan Emtage creates FTP indexing search tool Archie. One year later, Mark McCahill introduces the alternative Gopher. Veronica (Archie’s girlfriend in the comic books, and the “grandmother of search engines”) appears on the scene in 1992, spidering Gopherspace texts, and Jughead is arriving in ‘93.
- 1990-1993: WWW, and WWWW : In the meantime, the World Wide Web, created by Tim Berners-Lee* and released by CERN (the European Organization for Nuclear Research) in ‘91, is starting to take off. And 1993, the time the first web browser Mosaic takes the world by storm, also sees the first acclaimed Web robot, Matthew Gray’s World Wide Web Wanderer. Martijn Koster announces meta-tag spidering Aliweb in late ‘93.
- 1994: Search Engines See the Light : In early 1994, Jerry Yang and David Filo of Stanford University start Yahoo!* in their attempt to exert some kind of order on an otherwise anarchic collection of documents. Some months later in Washington, Brian Pinkerton’s WebCrawler is getting to work; over at Carnegie Melon, Dr. Michael Maldin creates Lycos (the name comes from the Latin “wolf spider”).
- 1995-1997: Dot-Com Rising : Metacrawler, Excite (late 1995), AltaVista (late 1995), later Inktomi/ HotBot (mid-1996), AskJeeves and GoTo; more and more search engines appear. Yahoo, actually a directory, is the leader, but AltaVista — meaning”a view from above”, and being a wordplay on (Palo) Alto-Vista; — launched in 1995 (and bought by Compaq in 1997) is gaining popularity.
- 1998-2002: Google et al : It’s late 1998. Stanford’s Larry Page and Sergey Brin reinvent search ranking technology with their paper “The Anatomy of a Large-Scale Hypertextual Web Search Engine” and start what some time later becomes the most successful search engine in the world. The topic about Search engine optimization becomes bigger and bigger field, with experts trying to boost rankings of commercial websites.
- 2003: Searching Today : These days, we can find more than ever, faster than dreamed of, but we’re also taking it for granted. Information at your fingertips; when you have a question, fire up Google. The answer’s out there.

Search Engine Component
Basically there are 4 component that build a search engine, such as :
- The spider is a program that goes out across the internet, looks for and gathers up web
pages.
- The database is where the spider will store the pages that it finds.
- The search engine website, e.g. google.com, is where searchers go to pull up information from the database.
- The algorithms are programs that determine which sites will come up when searchers type in
a query at the search engine website.
