You can use the below call to get only the required fields mentioned in Ranger UI.
curl -o ranger.query --negotiate -u : -X GET "http://<ambari-infra-solr-instance-hostname>:8886/solr/ranger_audits_shard1_replica1/select?q=*%3A*&fq=evtTime%3A%5B2017-06-11T10%3A44%3A00Z+TO+NOW%5D&fl=policy,evtTime,reqUser,repo,resource,resype,access,result,enforcer,cliIP,cluster,event_count&sort=evtTime+desc&start=0&rows=307600&wt=csv&version=2"
Depending on what all logs you want to pull adjust the evtTime, the above query pulls all the audit records, change the evtTime to the timestamp of the first record in ranger.
