[id="{upid}-{api}"]
=== Index API

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

An +{request}+ requires the following arguments:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-string]
--------------------------------------------------
<1> Index
<2> Type
<3> Document id
<4> Document source provided as a `String`

==== Providing the document source
The document source can be provided in different ways in addition to the
`String` example shown above:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-map]
--------------------------------------------------
<1> Document source provided as a `Map` which gets automatically converted
to JSON format

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-xcontent]
--------------------------------------------------
<1> Document source provided as an `XContentBuilder` object, the Elasticsearch
built-in helpers to generate JSON content

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-shortcut]
--------------------------------------------------
<1> Document source provided as `Object` key-pairs, which gets converted to
JSON format

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

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-routing]
--------------------------------------------------
<1> Routing value

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-timeout]
--------------------------------------------------
<1> Timeout to wait for primary shard to become available as a `TimeValue`
<2> Timeout to wait for primary shard to become available as a `String`

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-refresh]
--------------------------------------------------
<1> Refresh policy as a `WriteRequest.RefreshPolicy` instance
<2> Refresh policy as a `String`

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

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-version-type]
--------------------------------------------------
<1> Version type

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-op-type]
--------------------------------------------------
<1> Operation type provided as an `DocWriteRequest.OpType` value
<2> Operation type provided as a `String`: can be `create` or `update` (default)

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-pipeline]
--------------------------------------------------
<1> The name of the ingest pipeline to be executed before indexing the document

include::../execution.asciidoc[]

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

The returned +{response}+ allows to retrieve information about the executed
 operation as follows:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-response]
--------------------------------------------------
<1> Handle (if needed) the case where the document was created for the first
time
<2> Handle (if needed) the case where the document was rewritten as it was
already existing
<3> Handle the situation where number of successful shards is less than
total shards
<4> Handle the potential failures

If there is a version conflict, an `ElasticsearchException` will
be thrown:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-conflict]
--------------------------------------------------
<1> The raised exception indicates that a version conflict error was returned

Same will happen in case `opType` was set to `create` and a document with
same index, type and id already existed:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-optype]
--------------------------------------------------
<1> The raised exception indicates that a version conflict error was returned
