Ok. I should also note that scroll queries are not supported.
> Create a new ElasticSearch processor that supports the JSON DSL

> Key: NIFI-4325
> URL: https://issues.apache.org/jira/browse/NIFI-4325
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Mike Thomsen
> Priority: Minor
>
> The existing ElasticSearch processors use the Lucene-style syntax for
> querying, not the JSON DSL. A new processor is needed that can take a full
> JSON query and execute it. It should also support aggregation queries in this
> syntax. A user needs to be able to take a query as-is from Kibana and drop it
> into NiFi and have it just run.
