>            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.
