Hi, To eliminate any issues that might be happening due to curl, try running the command from your browser.
http://localhost:8988/solr/document2/stream?expr=search(document3,zkHost=" 127.0.0.1:2181",q="*:*",fl="document_id, sender_msg_dest", sort="document_id asc",qt="/export") I think most browsers will url encode the expression automatically, but you can url encode also using an online tool. Also you can remove the zkHost param and it should default to zkHost your solr is connected to. If you still get an error take a look at the logs and post the full stack trace to this thread, which will help determine where the problem is.
