"基于Java的搜索引擎设计与实现：解决网络信息搜索难题"

search engine is the best solution to this problem. This paper first introduces the system structure of internet-based search engines in detail, and then explains in detail from the three aspects of web crawlers, indexing engines, and web servers. In order to have a better understanding of this technology, I personally implemented my own search engine - a news search engine. The news search engine parses and searches from specified web pages according to hyperlinks, indexes each news item found, and adds it to a database. Then, the web server receives client requests and searches for matching news items from the index database. In addition to detailing the technical core of search engines in the chapter, I also combined the implementation code of the news search engine to explain, with illustrations and text, making it easy to understand. Keywords: search engine; web crawler; search strategy.
