A search engine is a software system designed to conduct web searches, and almost all web search engines obtain their information by crawling the web from site to site. In the early 1990s, when the World Wide Web did not exist, there were search tools such as Archie and Gopher in order to query files scattered in various distributed hosts, and it has been 31 years since then.
Early search engines had limited functions, and even website indexing/updating had to be maintained manually. Until July 1994, Lycos launched robot-based data mining technology and supported the relevance ranking of search results, and was the first to use automatic web page summaries in search results.
Since 2002, many companies have been attracted by the prospect of the search market and the myth of Google, and actively entered the search engine market to seek a place. But unfortunately, many companies use rogue means to promote their own search engines. The commonly used means are browser hijacking, malicious bundling of adware/spyware, etc. Typical companies that are relatively bad are Zhongsou, 3721 and so on.
The most popular search engine in the world, Google (accounting for 92.96% of the global market), was born in 1998, while the most popular Chinese search engine, Baidu, was founded in January 2000 by Li Yanhong and his friend Xu Yong.
It can be said that the popular search engine has been developed for 21 years. It can be said that the search engine has been accompanied by the development of the entire Internet. But in recent years, with the popularity of mobile applications and the explosion of social media, do traditional WEB search engines still have prospects for development? At least the status of WEB search engines as the largest traffic portal is beginning to shake.
Unlike web pages, mobile apps are not suitable for search engines to crawl their content because of their relatively closed nature. In addition, text search has begun to fail to meet the needs of users. The technological change in search for information such as voice, video, and images will also be a direction for future development.
Therefore, traditional search engines will likely develop towards knowledge-based search engines, providing searchers with more accurate and applicable information.
