Name	Type	Description
aggregatable	boolean	Whether this field can be aggregated on all indices.
indices	Indices	The list of indices where this field has the same type family, or null if all indices have the same type family for the field.
meta	Metadata	Merged metadata across all indices as a map of string keys to arrays of values. A value length of 1 indicates that all indices had the same value for this key, while a length of 2 or more indicates that not all indices had the same value for this key.
metadata_field	boolean	Whether this field is registered as a metadata field.
metric_conflicts_indices	IndexName[]	The list of indices where this field is present if these indices don’t have the same time_series_metric value for this field.
non_aggregatable_indices	Indices	The list of indices where this field is not aggregatable, or null if all indices have the same definition for the field.
non_dimension_indices	IndexName[]	If this list is present in response then some indices have the field marked as a dimension and other indices, the ones in this list, do not.
non_searchable_indices	Indices	The list of indices where this field is not searchable, or null if all indices have the same definition for the field.
searchable	boolean	Whether this field is indexed for search on all indices.
time_series_dimension	boolean	Whether this field is used as a time series dimension.
time_series_metric	MappingTimeSeriesMetricType	Contains metric type if this fields is used as a time series metrics, absent if the field is not used as metric.
