Im trying to update a 2.3.0 plugin to 6.6.1, and I can't find the new way of executing a template, current code:
ByteReferece byteRef = ...
SearchRequest searchRequest = new SearchRequest();
client.search(searchRequest, new RestStatusToXContentListener<>(channel, response));
To shad some light or context on the plugin, it is executing a query on a slightly different DSL that include more information about the request, eventually it needs to executed a templated request that accept a list of parameters that are resolved on the plugin side (es node).
