An index can be deleted together with its documents, shards, and metadata. Kibana components that are tied to it, like data views, visualizations, or dashboards, are not deleted.  The data stream's current write index cannot be deleted. You must roll the data stream over in order to build a new write index before you can delete the old one. The previous write index can then be deleted using the remove index API.  Request  DELETE /  Path parameters    - Wildcards (*) and _all are not supported by default for this argument. Set the action to utilize _all or wildcards. cluster setting for destructive requires name is false.  Query parameters  allow_no_indices - (Boolean, optional) If this is not the case, the request fails if any wildcard expression, index alias, or _all value only targets closed or missing indices. Even if the request is directed at other open indices, this behavior will still occur. For instance, if an index starts with foo but no index starts with a bar, a request targeting foo*, bar* produces an error.  Defaults to true.  expand_wildcards - The kind of index that can match wildcard patterns. This option controls whether wildcard expressions match hidden data streams if the request can target specific data streams. supports values with commas between them, such as open and hidden. Valid values include  all - Match any data stream or index, even those that are concealed.  open - Match open, non-hidden indices. Also matches any non-hidden data stream.  closed - Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.  hidden - Match hidden data streams and hidden indices. Must be combined with open, closed, or both.  none - Wildcard patterns are not accepted. ignore_unavailable  (Optional, Boolean) If false, the request returns an error if it targets a missing or closed index. Defaults to false.  master_timeout  (Optional, time units) Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error. Defaults to 30s.  timeout  (Optional, time units) Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error. Defaults to 30s.
