Abstract:
The evolution of the earch engines goes along with the development of the internet, for the convenience of the customers by letting them have easiest and fastest way to get the information that they needed from the data of oceans of information. It has a history of coming into being on demands, fast development, and then Wars Of Search Engines, the changing of ways to make money, and now there are several relatively stable giant kingdoms of the searching-engine business with some active new trends popping up.

Key words: Search engine, evolution, history, development

Let's start taking about the evlolution of search engines from the very beginning of internet. In the very beginning of the development of the internet, there were not so many websites, and the search for information was easy. However, with the leaping and jumping development of the internet, the searching for information became difficult, like searching for a needle in oceans. Hence, there was a demand for professional search and easy search, and the search engine industry came into being at that time.

The ancestor of search engines in modern sense, Archie, was invented in 1990 by a student from McGill University, named Alan Emtage. Although the World Wide Web had not yet emerged, but the network file transfer was still quite frequent. However, due to the large number of documents scattered in the various decentralized FTP servers, it was very inconvenient to get inquiries. So, Alan Emtage thought of the development of a document which could search for documents from the system. Archie at the time was the most popular repository of Internet files, Anonymous FTP sites. Archie is short for "Archives" but the programmer had to conform to UNIX standards of short names. The working theory of Archie is similar to modern search engines, and it searches information automatically, and offers indexes, which allows visiting by expressions.

What Archie did for FTP sites Veronica did for Gopherspace. Veronica was created in 1993 at the System Computing Services of University of Nevada. Jughead was a similar Gopherspace index. It is much like Archie, however, it could search not only documents but also web pages.

At that time, "Robot" was a popular word among the programmers.Retrieval Scott Weiss describes a robot in the Glossary for Information as: "a program that scans the web looking for URLs. It is started at a particular web page, and then accesses all the links from it. In this manner, it traverses
