Joseph Percivall commented on NIFI-3576:
----------------------------------------
There are a couple examples, such as RouteOnAttribute, RouteOnContent, and
QueryRecord but the best example for this use case is probably LookUpRecord[1].
Ah looks like it's still an open ticket to add DisplayName to Relationships[2].
Definitely, would rather not break people's flows. Let's just change up the
description to better match.

> QueryElasticsearchHttp should have a "Not Found"/"Zero results" relationship

> Key: NIFI-3576
> URL: https://issues.apache.org/jira/browse/NIFI-3576
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Joseph Percivall
> Assignee: Otto Fowler
> Priority: Minor
>
> In the event of a successful call, QueryElasticsearchHttp always drops the
> incoming flowfile and then emits pages of results to the success
> relationship. If the search returns no results then no pages of results are
> emitted to the success relationship.
> The processor should offer other options for handling when there are no
> results returned.
