英文摘要：

Based on the analysis of BF calculate way, KMP calculate way, BMH calculate way, SUNDAY calculate way and ZZL calculate way, this paper puts forward a rapid string precision calculate way used for a keyword index, and gets basic conclusion through an experiment. Finally it points out that the faintness matches the main differentiation that matches with precision and tally up to the full text.
