Design and Implementation of an Indexing Method Based on Fields for Elasticsearch

Having the knowledge of application and version of nodes on the Internet is very important for warning about and managing vulnerabilities. And designing a search engine for the application and version of the nodes is of great importance for the Internet safe guard. In order to meet the users´ needs of searching the information of IP address and domain name, the paper proposed a method to convert IP address and analyze domain names. As more and more information needs to be indexed, it will take a longer time to query in the index, which will influence the users´ experience. To solve these problems, this article proposed a method to create the index based on fields, and the corresponding compressing algorithm is used to guarantee the compression efficiency. The experiment shows that the proposed method can meet the users need in querying, reduce the impression efficiency, as well as reduce the search time as the indexes counts increases.
