Abstract：The purpose of this paper is to solve the problem of low search efficiency and single matching degree of personal information retrieval service under the condition of large amount of data. A comprehensive search system for Chinese database is designed and implemented. The system takes android as the client platform, and uses SSM development framework in the background to integrate four functional modules, including user management, data import, information retrieval and system settings. Relying on Logstash, the data is synchronously migrated from data source to full-text search engine.Combining with full-text search and database query technology, this paper provides a unified query portal and efficient search service. In order to ensure the security of sensitive data, this paper realize interface level authority authentication and strictly control the retrieval authority of different users. According to the test and online practice, the system runs stably and searches accurately and efficiently. At present, it has been applied in the core system of related industries.
