摘　　要：基于Lucene实现了一种高效的WEB全文检索框架Qlucene。该框架针对中小型WEB应用的硬件资源和数据量的实际情况,通过缓存机制和Index Reader无缝替换机制,在不丧失索引检索性能的同时,可以相对实时地进行索引的添加与更新。实践证明,Qlucene是一套Lucene在中小型WEB应用中的优秀解决方案。An enhanced full-text retrieval framework based on Lucene, named Qlucene, is developed here. This framework can afford web information retrieval. Given consideration to the realities of hardware resource and data capacity on small and medium-sized web sites, cache mechanism and seamless substitution mechanism of IndexReader are applied to this framework, by means of which index can be created and updated real time relatively. Meantime, Retrieval capabilities of lucene index can be avoided loss. Practice improves that Qlucene derived from Luence is the good settlement in the small and medium-sized web applications.
