> Add QueryElasticsearchHttp property to support no hits on original FF

> Key: NIFI-7036
> URL: https://issues.apache.org/jira/browse/NIFI-7036
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Joseph Gresock
> Assignee: Joseph Gresock
> Priority: Minor
> Fix For: 1.11.0

> Time Spent: 10m
> Remaining Estimate: 0h

> One use case that isn't supported by the current implementation of query-info
> and "no hits" being returned by QueryElasticsearchHttp is when you want to be
> able to check if there are hits in ES without overwriting the contents of the
> flow file. Currently if your search returns with no hits, this fact is only
> reported in the query-info relationship, which does not have the contents of
> the incoming flow file.
> I propose adding a value to "Routing Strategy for Query Info" called "Append
> as Attributes", which will simply add the query info attributes (es.query.url
> and es.query.hitcount) to the incoming flow file (which is routed to success,
> retry, or failure) instead of being added to flowfile that goes to the
> query-info relationship.
