Now my springmvc project requires the use of elasticsearch to achieve full-text search, and the need to install searchguard plug-ins to ensure data security, but how to install searchguard plug-in elasticsearch inherited to the web project? please give me some ideas. Here is my general situation. 1. Running Elasticsearch in-process in my SpringMVC web project. 2. Using a Transport Client to communicate with ES. 3. The version of ES is 2.3.4, and the version of SG is v188.8.131.52.
