# 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
elasticsearch-5.2.0\config\scripts\page-query-by-brand.mustache
{
"from": {{from}},
"size": {{size}},
"query": {
"match": {
"brand.keyword": "{{brand}}"
}

TIP
注意要重启 es，注意模板中的内容是你对应的。一定要确认不要搞错
@Test
public void pageQueryTest() {
HashMap<String, Object> scriptParams = new HashMap<>();
scriptParams.put("from", 0);
scriptParams.put("size", 1);
scriptParams.put("brand", "宝马");
SearchTemplateResponse searchTemplateResponse = new SearchTemplateRequestBuilder(client)
.setScriptType(ScriptType.FILE)
.setScript("page-query-by-brand") // page-query-by-brand.mustache
.setScriptParams(scriptParams)
.setRequest(new SearchRequest("car_shop").types("sales"))
.get();
SearchResponse response = searchTemplateResponse.getResponse();
System.out.println(searchTemplateResponse.getResponse());
SearchHit[] hits = response.getHits().getHits();
for (SearchHit hit : hits) {
System.out.println(hit.getSourceAsString());
}
client.close();
}
