我正在将一个java应用程序从ElasticSearch高级客户端迁移到java API客户端。在ElasticSearchjava高级客户端中有一个SearchTemplateRequest类。但是我在java api客户端中找不到任何对应的类。有人能帮忙吗？旧代码片段如下。

public SearchTemplateResponse getScriptResponse(String indexName, String scriptName, Map<String, Object> scriptParams) throws IOException {
        SearchTemplateRequest request = null;
        SearchTemplateResponse response = null;
        try {
            SearchTemplateRequest request = new SearchTemplateRequest();
        request.setRequest(new SearchRequest(new String[] { indexName }, trackTotalHitsSourceBuilder()));
        request.setScriptType(ScriptType.STORED);
        request.setScript(scriptName);
        request.setScriptParams(scriptParams);
        request.getRequest().source().trackTotalHits();
        response = getClient().searchTemplate(request, RequestOptions.DEFAULT);
        } catch (Exception e) {
            throw e;
        }
        return response;
    }

I'm using above code block to get the response of bucket aggregation with script query.
