基于索引过滤实现搜索引擎中的访问控制

摘要

互联网络发展到今天，搜索引擎已经得到了广泛应用。如今，搜索引擎在内联网络的应用也逐步增多，由于内联网络具有分权访问特点，所以必须在搜索过程中实现安全访问，保证角色权限和所能搜索到的信息的安全等级相对应。本文提出一种基于索引过滤实现安全搜索的策略，该策略能保证信息搜索的准确性和安全性。%With the development of Internet , search engine has been widely applied .Now the application of search engine in the inline network is also gradually increasing .Inline network has the characteristics of separation of access , so it is necessary to real-ize security access in search process , and role permissions also conform to the security level of information searched .This paper proposes a kind of search strategy to realize security based on index filter , this strategy can ensure the accuracy and security of in-formation search.
