tag::allow-no-match-transforms1[]
Specifies what to do when the request:
+
--
* Contains wildcard expressions and there are no {transforms} that match.
* Contains the `_all` string or no identifiers and there are no matches.
* Contains wildcard expressions and there are only partial matches.

The default value is `true`, which returns an empty `transforms` array when
there are no matches and the subset of results when there are partial matches.

If this parameter is `false`, the request returns a `404` status code when there
are no matches or only partial matches.

The default value is `true`, which returns a successful acknowledgement message
when there are no matches. When there are only partial matches, the API stops
the appropriate {transforms}. For example, if the request contains
`test-id1*,test-id2*` as the identifiers and there are no {transforms}
that match `test-id2*`, the API nonetheless stops the {transforms}
that match `test-id1*`.

If this parameter is `false`, the request returns a `404` status code when there

tag::transform-settings-max-page-search-size[]
Defines the initial page size to use for the composite aggregation for each
checkpoint. If circuit breaker exceptions occur, the page size is dynamically
adjusted to a lower value. The minimum value is `10` and the maximum is `10,000`.
The default value is `500`.

(Optional, string) ID of the task to return
(`node_id:task_number`).

tag::terminate_after[]
`terminate_after`::
(Optional, integer) The maximum number of documents to collect for each shard,
upon reaching which the query execution will terminate early.

tag::timeout[]
tag::master-timeout[]
`master_timeout`::
(Optional, <<time-units, time units>>) Specifies the period of time 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`.
end::master-timeout[]

`timeout`::
(Optional, <<time-units, time units>>) Specifies the period of time to wait for
a response. If no response is received before the timeout expires, the request
fails and returns an error. Defaults to `30s`.

tag::type[]
`<type>`::
(Optional, string)
Comma-separated list or wildcard expression of types
used to limit the request.

tag::transform-id[]
Identifier for the {transform}. This identifier can contain lowercase
alphanumeric characters (a-z and 0-9), hyphens, and underscores. It must start
and end with alphanumeric characters.
end::transform-id[]

tag::transform-id-wildcard[]
Identifier for the {transform}. It can be a {transform} identifier or a wildcard
expression. If you do not specify one of these options, the API returns
information for all {transforms}.
end::transform-id-wildcard[]

tag::trigger-count[]
The number of times the {transform} has been triggered by the scheduler. For
example, the scheduler triggers the {transform} indexer to check for updates
or ingest new data at an interval specified in the
<<put-transform-request-body,`frequency` property>>.

tag::cat-v[]
`v`::
(Optional, boolean) If `true`, the response includes column headings.
Defaults to `false`.

tag::version[]
`version`::
(Optional, boolean) If `true`, returns the document version as part of a hit.
end::version[]

tag::doc-version[]
`version`::
(Optional, integer) Explicit version number for concurrency control.
The specified version must match the current version of the document for the
request to succeed.
end::doc-version[]

tag::segment-version[]
Version of Lucene used to write the segment.

--
(Optional, string) The number of shard copies that must be active before
proceeding with the operation. Set to `all` or any positive integer up
to the total number of shards in the index (`number_of_replicas+1`).
