Hello,

I'm using [Elasticsearch input plugin](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-elasticsearch.html) with [Csv output plugin](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-csv.html) as part of my pipeline.

now, generated CSV file has skip fields that are NULL in elasticsearch's document and that presents an issue as I can't really identify these fields, as generated file's fields are out of order...

How can I include field-names into generated CSV file at the top?

Please advise.

Thanks to `darkmoonvt` @IRC, the answer was easier than I thought) and even though it doesn't add field-names on top of CSV file, at least now each field is identifiable)
