Given specified query parameters, creates an Elasticsearch query to run. Any unspecified template parameters will be
assigned their default values if applicable. Returns the specific Elasticsearch query that would be generated and
run by calling <<search-application-search,search application search>>.

[[search-application-render-query-request]]
==== {api-request-title}

`POST _application/search_application/<name>/_render_query`

[[search-application-render-query-prereqs]]
==== {api-prereq-title}

Requires read privileges on the backing alias of the search application.

[[search-application-render-query-request-body]]
==== {api-request-body-title}

`params`::
(Optional, map of strings to objects)
Query parameters specific to this request, which will override any defaults specified in the template.

[[search-application-render-query-response-codes]]
==== {api-response-codes-title}

`404`::
Search Application `<name>` does not exist.

[[search-application-render-query-example]]
==== {api-examples-title}

The following example renders a query for a search application called `my-app`. In this case, the `from` and `size`
parameters are not specified, so default values are pulled from the search application template.
