Features of Baidu search engine

1. Information processing method based on word combination. It cleverly solves the problem of understanding Chinese information and greatly improves the search accuracy and query accuracy.

2. Supports mainstream Chinese encoding standards. It includes GBK (Chinese character internal code extension specification), GB2312 (simplified), and BIG5 (traditional), and can be converted between different encodings.
3. Intelligent relevance algorithm. The correlation evaluation is performed based on the combination of content and super-chain analysis, which can objectively analyze the information contained in the web page, thus maximizing the relevance of the search results.
4. The search results can indicate a wide range of webpage attributes (such as the title, URL, time, size, encoding, and summary), and highlight the user's query string, so that you can determine whether to read the original text.
5. Baidu search supports secondary retrieval (also known as progressive retrieval or forced retrieval ). You can continue searching in the last search result and gradually narrow down the search scope until the minimum and most accurate result set is reached. This makes it easier for users to find content they are really interested in massive amounts of information.
6. Smart recommendation technology for search keywords. After the first search, you will be prompted for the relevant search terms to help you find more relevant results. Statistics show that the search volume can be increased by 10-20%.
7. Using multithreading technology, efficient search algorithms, stable UNIX platforms, and localized servers ensures the fastest response speed. Baidu search engine provides search services in China, which can greatly shorten the retrieval response time (the average response time of a search is less than 0.5 seconds)
8. Multiple service methods are available, including one week, two weeks, and four weeks. Web page updates can be completed within seven days. It is the fastest updated Chinese search engine with the largest data volume.
9. The retrieval result output supports content, website, content, and website. You can select a time range to improve your search efficiency.
10. Intelligent and scalable search technology ensures the fastest collection of Internet information. With the world's largest Chinese information database, the database provides users with the most accurate, extensive, and time-sensitive information to provide a solid foundation.
11. Distributed architecture, well-designed optimization algorithms, and fault tolerance design ensure high availability, scalability, high performance, and high stability of the system at large traffic volumes. Each part adopts N + 1 redundancy design, and one server is in standby state at all times. Therefore, the entire system can provide high availability and high stability services within 99.9% of the time.
12. High configurability allows the search service to meet the needs of different users. In terms of search scheduling, relevance evaluation, content filtering, and display methods, the customer provides configurable means to make the system flexible and adaptive. The ICP site calls the search service by calling the application programming interface (API) of Baidu search engine. They decide the display method of the search results and add their own ads and company icons (logos ).
13. Advanced web page dynamic summary display technology. You can dynamically abstract the text that contains any position of the user query string on the webpage, making it easier and quicker for you to read and judge the search results.
14. The unique Baidu snapshot cleverly solves the endless link problems frequently encountered by search users. Baidu search engine has previewed various websites and taken snapshots of webpages to store a large number of emergency webpages for users. Baidu snapshot not only downloads extremely fast, but also marks user query strings in different colors on the webpage.
15. Multiple advanced search syntaxes are supported to make user queries more efficient and the results more accurate. "+" (AND), "-" (NOT), "|" (OR), "site:", "link:", other efficient search syntaxes will be added.
