This paper makes a research on the exact string matching, proposed a nested classification string matching algorithm. This paper based on the KMP algorithm, constructs the multi-level string matching and use the KR algorithm calculates the next function quickly, in order to replace the traditional KMP algorithm which is using the recursive thinking to calculate the next[j] function value in the large number of pattern string under the premise. Through the use of this method we can reduce the number of matches thereby raising the efficiency.
