What is the Best Way to Search the Internet?

Early search engines collected the addresses of resource servers in the Internet, divided them into different directories based on the types of resources they provided, and classified them layer by layer. People looking for the information they want can enter it layer by layer according to their classification, and they can finally reach their destination and find the information they want. This is actually the most primitive way, only when there is not much information on the Internet. As the information on the Internet grows geometrically, there are real search engines. These search engines know the beginning of each page on the website, then search all the hyperlinks on the Internet, and put all the words representing the hyperlinks into a database. . This is the prototype of today's search engines. ^[1]
