摘　　要：讨论了跨库检索的产生原因和实现方式,并借鉴元搜索引擎原理,设计了一个跨库检索系统模型,并就其检索代理模块在.NET环境下的实现进行了详细阐述。Frequently a user's information needs are stored in the databases of multiple search platforms. It is inconvenient and inefficient for an ordinary user to invoke multiple databases and identify useful documents from the returned result. To support unified access to multiple databases, a federated searching engine can be constructed. This article presents a model of federated searching software component architecture, and introduces the implementation of search agent module in. Net framework.
