I am using solr 7.4 version. I am trying to export data using streaming expressions.
Following is the simple curl query that i am using. I am indexing my data and testing the following query.
curl --data-urlencode 'expr=search(collection1,
q="text:solar",
fl="id",
sort="id asc",
qt="/export")' http://localhost:8983/solr/collection1/stream
when i run above query with initial few documents indexed, it is working fine. After indexing few thousand documents (around , i am getting the following error for the same query.
EXCEPTION":"java.util.concurrent.ExecutionException: java.io.IOException: --> http://localhost:8983/solr/collection1/: An exception has occurred on the server, refer to server log for details."
I've looked into my solr logs and the following is the error info

Is it because new documents have something unusual in their content? Even if that is the case, i am requesting only one field which is id and there is nothing unusual about it.
Also, to mention, if i give q="*:*" it is working fine (which is kind of weird)
Any idea what what is issue here ?
