time or later on through the relevant setter method.

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

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

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-alias]
--------------------------------------------------
<1> One or more aliases to look for

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-indices]
--------------------------------------------------
<1> The index or indices that the alias is associated with

["source","java",subs="attributes,callouts,macros"]

<1> Setting `IndicesOptions` controls how unavailable indices are resolved and
how wildcard expressions are expanded
