    ​kind=aws_ec2_snapshot, ..., account=poweruser-team

  2. Pipe the search command into the dump command:

    > search is(aws_ec2_snapshot) and encrypted=false | dump
    ​reported:
    ​  id: /aws/ec2/123
    ​  name: some-name
    ​  ctime: '2022-12-05T22:53:14Z'
    ​  kind: aws_ec2_snapshot
