If you do not specify which columns to include, the API returns the default
columns. If you explicitly specify one or more columns, it returns only the
specified columns.
+
Valid columns are:

`create_time`, `ct`:::
The time when the trained model was created.

`created_by`, `c`, `createdBy`:::
Information on the creator of the trained model.

`data_frame_analytics_id`, `df`, `dataFrameAnalytics`:::
Identifier for the {dfanalytics-job} that created the model. Only displayed if 
it is still available.

`description`, `d`:::
The description of the trained model.

`heap_size`, `hs`, `modelHeapSize`:::
(Default)
The estimated heap size to keep the trained model in memory.

`id`:::
(Default)
Idetifier for the trained model.

`ingest.count`, `ic`, `ingestCount`:::
The total number of documents that are processed by the model.

`ingest.current`, `icurr`, `ingestCurrent`:::
The total number of document that are currently being handled by the trained 
model.

`ingest.failed`, `if`, `ingestFailed`:::
The total number of failed ingest attempts with the trained model.

`ingest.pipelines`, `ip`, `ingestPipelines`:::
(Default)
The total number of ingest pipelines that are referencing the trained model.

`ingest.time`, `it`, `ingestTime`:::
The total time that is spent processing documents with the trained model.

`license`, `l`:::
The license level of the trained model.

`operations`, `o`, `modelOperations`:::
(Default)
The estimated number of operations to use the trained model. This number helps 
measuring the computational complexity of the model.

`version`, `v`:::
The {es} version number in which the trained model was created.
