A Water Conservancy Metadata Searching and Sharing Platform Based on ElasticSearch

With the development of water conservancy industry informatization,the massive,multi-source and heterogeneous data sharing and discovery become a hot research area. This paper presents the design and implementation of a metadata search platform based on Elastic Search,puts forward a solution of water conservancy heterogeneous data and builds the index on massive data. The multi-tenant access control policy is used to ensure the consistency and security of user data. The Rest service encapsulate index to provide searching and multi-granularity sharing. Application shows that the platform can ensure users accurately and efficiently to obtain the water conservancy industry data,save the water conservancy construction cost of unit search system.
