1. An online search method accounting for relevance and difference, comprising:
S1: determining an initial search result set having n candidate results based on results returned by a search engine according to a query request input by a user, wherein the initial search result set is D={d1,d2, . . . , dn};
S2: using a semantic matrix to describe attribute characteristics of documents corresponding to the candidate results;
S3: calculating similarities among the documents according to the attribute characteristics of the documents, and then using a k-means algorithm to cluster the n candidate results into k-type clustering blocks D1, D2, . . . , Dk, wherein k<n;
S4: selecting a representative di* from each of the clustering blocks D1, D2, . . . , Dk; and
S5: constructing a final search result set D*={d1*, d2*, . . . , dk*} according to the selected representatives; and returning the final search result set to an interface provided by the search engine.
