针对企业异构信息在资源数量上和载体种类上不断攀升的情况,为了实现对全部异构信息资源进行统一检索并满足检索效率要求,设计了一个基于Solr的飞机故障异构信息检索系统。该系统首先针对异构信息特点设计索引结构,实现统一检索;然后并将各类异构数据按其对应索引结构生成索引文件,并导入至索引信息库,实现信息融合;最后基于Solr J API进行系统开发,实现各类复杂搜索功能,并结合专业词汇权重优化排序结果。实验结果证明,该系统能满足多种复杂搜索需求,有效解决了对企业异构信息资源的检索问题,为企业做出快速决策提供了技术支持。
In order to realize the uniform retrieval of all heterogeneous information resources and meet the retrieval efficiency requirements, a heterogeneous information retrieval system based on Solr is designed to deal with the increasing number of heterogeneous information and carrier types. The system first designs the index structure according to the characteristics of heterogeneous information and implements unified retrieval. Then it generates index files according to the corresponding index structure and imports them into the index information base to realize the information fusion. Finally, based on the Solr J API System development, to achieve all kinds of complex search functions, combined with professional vocabulary optimization sorting results. The experimental results show that the system can meet a variety of complex search needs, effectively solve the problem of enterprise heterogeneous information retrieval, and provide technical support for enterprises to make rapid decisions.
