Render Search Application Query

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.

Examples

The following example generates a query for a search application called my-app that uses the search template from the text search example:

resp = client.perform_request(
    "POST",
    "/_application/search_application/my-app/_render_query",
    headers={"Content-Type": "application/json"},
    body={
        "params": {
            "query_string": "my first query",
            "text_fields": [
                {
                    "name": "title",
                    "boost": 5
                },
                {
                    "name": "description",
                    "boost": 1
                }
            ]
        }
    },
)
print(resp)

const response = await client.searchApplication.renderQuery({
  name: "my-app",
  body: {
    params: {
      query_string: "my first query",
      text_fields: [
        {
          name: "title",
          boost: 5,
        },
        {
          name: "description",
          boost: 1,
        },
      ],
    },
  },
});
console.log(response);

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.
