 In previous versions of Elasticsearch, delete by query requests without an explicit query
 were accepted, match_all was used as the default query and all documents were deleted
 as a result. From version 6.0.0, a `DeleteByQueryRequest` requires an explicit query be set.

+The `count` value in the stats aggregation represents a doc count that shouldnn't require a formatted

+`String.valueOf(getCount())` if needed
