The Research and Implementation of Unified Search Service’s Key Technologies
统一检索服务关键技术的研究与实现

This paper analyzes and summarizes four types of digital library resources, including commercial database resources, Web resources, local self-built resources and OAI metadata harvesting resources, then the authors integrate these resources in different ways. Based on these resources, many services can be supplied. This paper focuses on the analysis and realization of unified search service, whose implementation mechanism and work flow are also introduced. Unified search service can achieve a good user experience by means of searching different resources through data request module, extracting data by data analyzer module, and using Ajax to show the dynamic display results to the users.
