Do I define a runtime field in the search request to carry the parameters of the script？

[cglcl]

Recently, I was using ElasticsearchRestTemplate and found that it seems that the parameters of the script cannot be carried when defining runtime fields in a search request. What should I do to carry the parameters?
Like this script:

double price = 0;
for (int i = 0; i < params._source.pool_quotas.length; ++i) {
            if (params._source.pool_quotas[i].pool_id==params.pool_id){
                       price += params._source.pool_quotas[i].hard_limit;
            }
}
emit(price);

it looks:

{
	"from": 0,
	"size": 10,
	"query": {
		"bool": {
			"should": [{
				"term": {
					"name": {
						"value": "wangfei",
						"boost": 1.0
					}
				}
			}],
			"adjust_pure_negative": true,
			"minimum_should_match": "1",
			"boost": 1.0
		}
	},
	"version": true,
	"explain": false,
	"runtime_mappings": {
		"duration": {
			"type": "double",
			"script": {
				"source": "double price = 0;for (int i = 0; i < params._source.pool_quotas.length; ++i) {if (params._source.pool_quotas[i].pool_id==params.pool_id){price += params._source.pool_quotas[i].hard_limit;}}emit(price);",
				"lang": "painless",
				"params": {
					"pool_id": "cddaca80-6480-45af-85c2-b09577db4396"
				}
			}
		}
	}
}

How can I implement a query like this？Thanks！

Maybe I have solved it, I inherited the class RuntimeField.

public class RuntimeFieldParam extends RuntimeField {

    private final String lang;
    private final Map<String, Object> params;

    public RuntimeFieldParam(String name, String type, String script,
                             String lang, Map<String,Object> params) {
        super(name, type, script);
        this.lang = lang;
        this.params = params;
    }

    @Nonnull
    @Override
    public Map<String, Object> getMapping() {
        Map<String, Object> map = super.getMapping();
        Object script = map.get("script");
        Map<String, Object> newScript = new HashMap<>();
        newScript.put("source", script);
        newScript.put("lang", this.lang);
        newScript.put("params", this.params);
        map.put("script", newScript);
        return map;
    }
}

Is there any other way besides this method?

Seems not currently. This would need to be added as an addition to the RuntimeField class.

OK, so I'll implement it like this for now.
