摘　　要：在研究云计算及移动搜索引擎的基础上,依据当前技术发展,提出了基于服务器集群的云检索系统模型,该模型由云信息层、云检索集群系统和用户查询框组成。对云检索集群系统中数据存储技术进行了深入研究,提出了分布式云检索数据存储方案。为了提高云检索执行效率,提出了以程序流为核心的云检索软件执行模式。该模型的测试结果表明,系统功能能正确实现,性能表现较好且稳定。通过该模型的示范,给海量信息检索技术提供了拓展思维的方案。Based on the study of cloud computing and mobile search engine, according to the development of current technology, we put forward the cloud retrieval system model based on clusters. The model consists of the cloud information layer,cloud retrieval cluster system, the user query box. We deeply studied distributed data storage technology in cloud retrieval system, and proposed program of cloud storage and retrieval of data structure. In order to improve the efficiency of parallel execution in cloud retrieval, put forward a program flow at the core of cloud retrieval software implementation of the model. The testing results of the model are shown that the system function can realize correctly, and its performance is good and steady. The demonstration of this model gives the retrieval technology of massive information a scheme to develop thinking.
