This postings format is the default PostingsFormat for Elasticsearch. It utilizes the MapperService to lookup a PostingsFormat per field. This allows users to change the low level postings format for individual fields per index in real time via the mapping API. If no specific postings format is configured for a specific field the default postings format is used.
