摘要
This paper presents a distributed search engine design of an on-line bookstore system. Sever-al principles are introduced such as database miniaturization,the entire structure and the main modules are explained in detail. Compared with a centralized structure,the distributed structure has several ad-vantages including high speed, efficient usage of network bandwidth, less security problems, etc. The system uses feedback of the users to judge the information quality, select search engines and update databases. So,the system performances are improved.
