Thanks for the reply. Except for the six standard fields, I also want to know the extra field. For example, in Solr we can extract the "album" field in MP3 file. Does this function also support in ElasticSearch? I just tested: I post a mp3 file into ES, but the fields of the mp3 file contains only the six fields.
Ideas? Thanks a lot.
