| Abstract: | DotLucene is a full-text search toolkit with opening-up source, available extension and good capa- bility. It can be easily embedded into a variety of applications to achieve full-text index and query, The arti- cle 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. |
