Before there were web <a href="http://bbbjyjyjyj.wz.cz/map.html">bbbjyjyjyj.wz.cz</a> search engines there was a complete list of all webservers. <a href="http://bffhfehhh.wz.cz/map.html">bffhfehhh.wz.cz</a> The list was edited by Tim Berners-Lee and hosted on the CERN webserver. One historical snapshot from 1992 remains.[1] As more and more webservers went online the central list could not keep up. On the NCSA site new servers were announced under the title "What's New!" but no complete listing existed any more.[2]
The very first tool <a href="http://dvdgrgregrge.wz.cz/map.html">dvdgrgregrge.wz.cz</a> used for searching on the (pre-web) Internet was Archie.[3] The name stands for "archive" without the "v." It was created in 1990 by Alan Emtage, a student at McGill University in Montreal. The program downloaded the directory listings of all the files located on public anonymous FTP (File Transfer Protocol) sites, creating a searchable database of file names; however, Archie did not <a href="http://grgre.wz.cz/map.html">grgre.wz.cz</a> index the contents of these sites <a href="http://qghryhytj.wz.cz/map.html">qghryhytj.wz.cz</a>.
The rise of Gopher <a href="http://efewfew.wz.cz/map.html">efewfew.wz.cz</a> (created in 1991 by Mark McCahill at the University of Minnesota) led to two new search programs, <a href="http://dwdwfqwfq.wz.cz/map.html">dwdwfqwfq.wz.cz</a> Veronica and Jughead. Like Archie, they searched the file names and titles stored in Gopher index systems. Veronica (Very Easy Rodent-Oriented Net-wide <a href="http://qgthjkyty.wz.cz/map.html">qgthjkyty.wz.cz</a> Index to Computerized Archives) provided a keyword search of most <a href="http://hthrjthrhr.wz.cz/map.html">hthrjthrhr.wz.cz</a> Gopher menu titles in the entire Gopher listings. Jughead (Jonzy's Universal Gopher <a href="http://fewfewefw.wz.cz/map.html">fewfewefw.wz.cz</a> Hierarchy Excavation And Display) was a tool for obtaining menu information from specific Gopher servers. While the name of the search engine "Archie" <a href="http://grtgrgr.wz.cz/map.html">grtgrgr.wz.cz</a> was not a reference to the Archie comic book series, "Veronica" and "Jughead" are <a hre
f="http://geh45h45h.mysteria.cz/map.html">geh45h45h.mysteria.cz</a> characters in the series, thus referencing their <a href="http://hhhhtrreet.wz.cz/map.html">hhhhtrreet.wz.cz</a> predecessor.
In June 1993, Matthew <a href="http://gggyhjhtj.wz.cz/map.html">gggyhjhtj.wz.cz</a> Gray, then at MIT, produced what was probably the first web robot, the Perl-based World Wide Web Wanderer, and used it to generate an index called 'Wandex'. The purpose of the Wanderer was to measure the size of the World Wide Web, which it did until late 1995. The search engine Aliweb appeared in November 1993. Aliweb did not use a web robot, but instead depended on being notified by website administrators of the existence at each site of an index file in a particular format.
JumpStation <a href="http://efweefw.wz.cz/map.html">efweefw.wz.cz</a> (released in December 1993[4]) used a web robot to find web <a href="http://dqwdwqdwq.wz.cz/map.html">dqwdwqdwq.wz.cz</a> pages and to build its index, and used a web form as the interface to its query program. It was <a href="http://hrryjytkut.wz.cz/map.html">hrryjytkut.wz.cz</a> thus the first WWW resource-discovery tool to combine the three essential features of a web search engine (crawling, indexing, and searching) as described below. Because of <a href="http://eeererrttg.wz.cz/map.html">eeererrttg.wz.cz</a> the limited resources available on the platform on which it ran, its indexing and hence <a href="http://fefewfwghyh.wz.cz/map.html">fefewfwghyh.wz.cz</a> searching were limited to the titles and headings found in the web pages the <a href="http://jyjtyrjuyter.wz.cz/map.html">jyjtyrjuyter.wz.cz</a> crawler encountered.
