ES Java API_基于search template实现按品牌分页查询模板

搜索模板的功能，java api怎么去调用一个搜索模板

page_query_by_brand.mustache

{

"from": {{from}},

"size": {{size}},

"query": {

"match": {

"brand.keyword": "{{brand}}"

}

}

}

SearchResponse sr = new SearchTemplateRequestBuilder(client)

.setScript("page_query_by_brand")

.setScriptType(ScriptService.ScriptType.FILE)

.setScriptParams(template_params)

.setRequest(new SearchRequest())

.get()

.getResponse();

System.out.println(searchHit.getSourceAsString());

}

client.close();

}
