Thank you for your answer. To 3.) The file is on server A, my program is on server B and solr is on server C. If I use a normal http(rest) post, my program has to fetch the file content from server A to Server B and then post it from server B to server C as there is no open connection between A and C. So the file has to be transmitted two times. Is there a way to tell solr to read the file _directly_ from Server A (e.g. via SMB)
