> FetchElasticsearchHttp allows users to select a single document from Elasticsearch in NiFi, but there is no way to run a query to retrieve multiple documents.
> We should add a QueryElasticsearchHttp processor for running a query and returning a flow file per result, for small result sets.  This should allow both input and non-input execution.  
> A separate ScrollElasticsearchHttp processor would also be useful for scrolling through a huge result set.  This should use the state manager to maintain the scroll_id value, and use this as input to the next scroll page.  As a result, this processor should not allow flow file input, but should retrieve one page per run.
