We are trying for find a plugin for Elasticsearch on par with Velocity Response Writer for Solr? https://lucene.apache.org/solr/guide/8_5/velocity-response-writer.html#velocity-response-writer
Basically, we want to leverage Elasticsearch to render HTML directly without an app engine. We would like to install an Apache/Nginx in front of Elasticsearch to do with URL rewrites and proxies the search request to Elasticsearch and let Elasticsearch respond HTML to Apache/Nginx and eventually back to the users. Any templating engine would work, like Velocity, Mustache or Handlebars. Please let us know if there is such a plugin or we need to write our own custom plugin. Thank you.
