The network search engine gathers the information of tens of thousands of sites, the main function is to help users search these sites, and also classify some good sites to facilitate users to find relevant information. [0003] Currently, many search technologies use Inverted Document Frequency (IDF) technology to search web pages. IDF was first proposed by Spark-Jones of Cambridge University, and it is an important technology in information retrieval. IDF can distinguish the proportion of a word to the meaning expression of a document. For example, there are many words such as "vector" in a document, but the word "vector" only appears in a small number of documents, then the word "vector" can distinguish this document very well, an...
