According to the docs, setting the detailed parameter on a request to _tasks API will return a description for each task - but when I set the parameter, even though the "description" field exists in the response, it is always empty.
I assume that not all tasks have a description, but according to the docs at least _bulk tasks should have a description:
"The new description field contains human readable text that identifies the particular request that the task is performing such as identifying the search request being performed by a search task like the example above. Other kinds of task have have different descriptions, like _reindex which has the search and the destination, or _bulk which just has the number of requests and the destination indices."
However, even for bulk tasks, there is no description.. is this a bug in ES (I am using 5.4.0) or in the docs?
