1. A system for searching information and displaying search results, the system comprising:

  • a web server comprising an inputting module that receives one or more keywords input from one or more client computers; and

    a search server comprising;

    an obtaining module that obtains search results according to the one or more keywords from a cache of the search server or from an index database, the search results comprising one or more documents;

    a calculating module that calculates a weight of each word of the documents in the search results, calculates a correlation between each cluster name and each document in the search results, and calculates a probability of each document occurring in each language module;

    a confirming module that confirms at least one cluster name according to the search results by comparing each weight and a defined cluster-name threshold, selecting the words that reach the defined cluster-name threshold, and deleting punctuations in the words that reach the defined cluster-name threshold according to a longest-word principle, and clusters each of the one or more documents in the search results into a corresponding cluster name according to the correlation, classifies each document in the search results into a corresponding field according to the probability, and thus obtains classified search results;

    a generating module that generates a cluster diagram according to the at least one cluster name and the clustered documents, and generates a cluster-classification diagram according to the classified search results and the generated cluster diagram;

    the web server further comprising an outputting module that outputs the generated cluster-classification diagram to the one or more client computers.
