摘　　要：全文检索是一种非常有效的信息检索技术,本文通过分析全文检索系统中静态索引技术的优缺点,以及影响动态性能的因素,提出一种基于互关联后继树模型的动态索引技术,该技术在不影响查询效率等性能的情况下,很好地解决了索引的更新问题,提高了索引的动态性能。Full-text retrieval is one of the most efficient technologies of information retrieving.This paper analy- ses the merits and fault of static index technology in full text retrieval system,discusses the factors which may impact the dynamic feature of index,then puts forwards a kind of dynamic index technology based on inter - rele- vant successive trees.This technology has good per- formance in solving the problem of updating index and enhancing its dynamic feature,while not affecting inquir- ing efficiency and other performances.
