Splunk CLI remote search parse _raw into fields

I am using a locally installed Splunk instance to perform a remote search using the CLI. splunk search "index=sandbox sourcetype=access http_status_code<400 earliest="10/01/2017:00:00:00" latest="10/02/2017:00:00:00"" -output csv -maxout 0 -max_time 0 -auth user:password -app remote_app -uri https://hostname:port > output.csv "access" is a sourcetype that is defined on the remote Splunk enterprise server. When I get the results, how can I parse the _raw field into the individual fields that have field extractions defined on the remote Splunk server.
