In enterprise information search environment, sensitivity of data security, diversity of data source and data formats, search for database are especial problems. In view of security and extensibility, the architecture of an enterprise search system named EISI is proposed using metadata technology. The unified description model of heterogeneous information resources in enterprise is proposed for the management of search objects that is unstructured or structured, and the multi-level multi-granular security control is implemented based on the model. EISI is implemented by integrating existed index technology. EISI can adjust itself to the change of data source and data formats. The results of practical application indicate that both structureddata and unstructureddata can be searched in security, moreover the requirements of data search can be met effectively.
