Kibana doesn't support attachment type plugin

[DreamRocker]

I am trying to use Kibana together with the attachment type plugin (https://github.com/elasticsearch/elasticsearch-mapper-attachments).
The problem is that the fields are not discovered correctly and with that the result table isn't useable.

So far I can see this happens since Kibana uses _source to determine the field list. But this list won't contain all the fields that the ES server actually adds with the plugin.

The _source contains something like:
"my_attachment" : {
"_content_type" : "application/pdf",
"_name" : "resource/name/of/my.pdf",
"content" : "... base64 encoded attachment ..."
}

The server extends this data but this is not visible in _source.

Kibana needs the fields to be properly mapped. If any given plugin does not do that we simply can't support it.
