摘　　要：文章详细介绍了一个自主开发的全文检索系统,它以XML文档的标签内容作为索引对象,定义了文档和文档属性等概念,采用B+树对文献信息构建索引,实现了基于Web的中英文混合检索。为全文数据库的底层实现提供了技术参考,也为系统进一步完成自适应主动推送服务提供必要的接口。The article introduces a self-developed full text index system, which takes XML document's label content as index target and defines the concepts of document, document attribute, etc. It applies B+ tree to index the literature and realizes web-based Chinese and English mixed index. Further, it provides technical references for the construction of full text database infrastructure, as well as necessary interface for the system to accomplish self-adaptive and active information recommendations.
