Render Search Application Queryedit
This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
Given specified query parameters, generates an Elasticsearch query using the search template associated with the search application or a default template if none is specified. Unspecified template parameters will be assigned their default values (if applicable). Returns the specific Elasticsearch query that would be generated and executed by calling search application search.
Requestedit
POST _application/search_application/<name>/_render_query
Prerequisitesedit
Requires read privileges on the backing alias of the search application.
Request bodyedit
-
params -
(Optional, map of strings to objects)
Query parameters used to generate the Elasticsearch query from the search template associated with the search application.
If a parameter used in the search template is not specified in
params, the parameter’s default value will be used.
The search application can be configured to validate search template parameters.
See the dictionary parameter in the put search application API for more
information.

Examplesedit
The following example generates a query for a search application called my-app that uses the search template from
the text search example:
POST _application/search_application/my-app/_render_query
{
"params": {
"query_string": "my first query",
"text_fields": [
{"name": "title", "boost": 5},
{"name": "description", "boost": 1}
]
}
}
A sample response:
{
"from": 0,
"size": 10,
"query": {
"multi_match": {
"query": "my first query",
"fields": [
"description^1.0",
"title^5.0"
]
}
},
"explain": false
}
In this case, the from, size, and explain parameters are not specified in the request, so the default values
specified in the search template are used.
