With the continuous expansion of information technology in the insurance industry, more and more business data is available in vertical areas, which inevitably brings great challenges to the storage and query efficiency of traditional structured databases. How to realize data redundancy backup and fast and efficient query has become a major problem of enterprise information technology. This paper presents a distributed search engine based on ElasticSearch, which combines with Logstash to collect data. It can filter, store and index vehicle data, and provide a unified query entry and efficient retrieval service for insurance policy issuing system. Practice shows that the system can achieve redundant backup of data and improve the efficiency of retrieving vehicle data. At present, it has been applied in the core system of insurance industry and achieved good results.
