Log Context

Log “key [{}]; from [{}]; to [{}]; doc_count [{}]” classname is geodistance-aggregation.asciidoc
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

     String key = entry.getKeyAsString();    // key as String
    Number from = (Number) entry.getFrom(); // bucket from value
