=== Open Index API

[id="{upid}-{api}-request"]
==== Open Index Request

An +{request}+ requires an `index` argument:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request]
--------------------------------------------------
<1> The index to open

==== Optional arguments
The following arguments can optionally be provided:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-timeout]
--------------------------------------------------
<1> Timeout to wait for the all the nodes to acknowledge the index is opened
as a `TimeValue`
<2> Timeout to wait for the all the nodes to acknowledge the index is opened
as a `String`

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-masterTimeout]
--------------------------------------------------
<1> Timeout to connect to the master node as a `TimeValue`
<2> Timeout to connect to the master node as a `String`

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-waitForActiveShards]
--------------------------------------------------
<1> The number of active shard copies to wait for before the open index API
returns a response, as an `int`
<2> The number of active shard copies to wait for before  the open index API
returns a response, as an `ActiveShardCount`

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-indicesOptions]

[id="{upid}-{api}-response"]
==== Open Index Response

The returned +{response}+ allows to retrieve information about the

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-response]
--------------------------------------------------
<1> Indicates whether all of the nodes have acknowledged the request
<2> Indicates whether the requisite number of shard copies were started for
each shard in the index before timing out
