基于DotLucene的全文检索及其在GIS中的应用

摘要

DotLucene is a full-text search toolkit with opening-up source,available extension and good capability. It can be easily embedded into a variety of applications to achieve full-text index and query. The article based on the studies of systemic structure and main function of DotLucene, full-text search engine DotLucene is introduced to GIS to rectify the inability of old GIS search function. This innovation realizes the resolution of selecting resources GIS need by means of context of the document instead of physical characteristics from the mass of information,and improves GIS' full-text search function.%DotLucene是一个开源的、可扩展的、高性能的全文检索工具包,它可以方便的嵌入到各种应用系统中实现全文索引和查询功能.在研究DotLucene的体系结构和主要功能模块的基础上,针对传统GIS查询功能中全文检索能力较弱的现状,将全文检索引擎DotLucene引入到GIS中,实现根据GIS文档资料的内容而不是其外部特征从海量文本资源中检索出GIS所关心的文档,扩展GIS的全文检索功能.
