-    By default, you must explicitly name the indices you are adding blocks to. To allow the adding of blocks to indices with `_all`, `*`, or other wildcard expressions, change the `action.destructive_requires_name` setting to `false`. You can update this setting in the `elasticsearch.yml` file or using the [cluster update settings](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-cluster-put-settings) API.

This behavior applies even if the request targets other open indices. For example, a request targeting `foo*,bar*` returns an error if an index starts with `foo` but no index starts with `bar`.

-`expand_wildcards`
-:   (Optional, string) Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as `open,hidden`. Valid values are:
-
-`all`
-:   Match any data stream or index, including [hidden](/reference/elasticsearch/rest-apis/api-conventions.md#multi-hidden) ones.

-:   (Optional, [time units](/reference/elasticsearch/rest-apis/api-conventions.md#time-units)) Period to wait for the master node. If the master node is not available before the timeout expires, the request fails and returns an error. Defaults to `30s`. Can also be set to `-1` to indicate that the request should never timeout.

-:   (Optional, [time units](/reference/elasticsearch/rest-apis/api-conventions.md#time-units)) Period to wait for a response from all relevant nodes in the cluster after updating the cluster metadata.

+## `TS` [esql-ts]
+
+The `TS` command is similar to the `FROM` source command,
+but with two key differences: it targets only [time-series indices](docs-content://manage-data/data-store/data-streams/time-series-data-stream-tsds.md)
+and enables the use of time-series aggregation functions
+with the [STATS](/reference/query-languages/esql/commands/processing-commands.md#esql-stats-by) command.
+
+**Syntax**
+
+```esql
+TS index_pattern [METADATA fields]
+```
+
+**Parameters**
+
+`index_pattern`
+:   A list of indices, data streams or aliases. Supports wildcards and date math.
+
+`fields`
+:   A comma-separated list of [metadata fields](/reference/query-languages/esql/esql-metadata-fields.md) to retrieve.
+
+**Examples**
+
+```esql
+TS metrics
+| STATS sum(last_over_time(memory_usage))
+```
