I understand thanks.

I set `type` following your example and I end up in `ES` with a field `type` (in `_source`) **and** a field `_type` in the meta data. They both have the same value, the one I used when setting `type`in `logstash`.

Should I deduce from this that the **field** called `type` in `logstash` is treated in a special way by the `elasticsearch` output plugin - by assuming that its value should also be used to populate `_type` before sending to `ES` ?
