elasticsearch 多条件查询 - filter过滤

过滤查询
例如
	票价必须少于40

方式1 restful api

filter表示过滤
	range 表示范围查询
		let 表示小于
		get 大于
		
POST  http://192.168.199.126:9200/film/dongzuo/_search/
{
  "query": {
    "bool": {
      "must": {
        "match": {
          "title": "战"
        }
      },
      "filter": {
        "range": {
          "price": {
            "lte": "40"
          }
        }
      }
    }
  }
}

方式2 Java接口实现

部分代码
private TransportClient client;

    private static String host="192.168.199.126";
    private static int port=9300; // 程序连接的端口

    // 配置settings 集群相关
    private static Settings.Builder settings = Settings.builder().put("cluster.name","my-application");


    @Before
    public void init() throws UnknownHostException {
        client = new PreBuiltTransportClient(settings.build())
                .addTransportAddress(new TransportAddress(InetAddress.getByName(host), port));

    }

    @After
    public void close(){
        if(client!=null){
            client.close();
        }
    }

@Test
public void searchMutil4()throws Exception{
    SearchRequestBuilder srb=client.prepareSearch("film").setTypes("dongzuo");
    QueryBuilder queryBuilder=QueryBuilders.matchPhraseQuery("title", "战");
    QueryBuilder queryBuilder2=QueryBuilders.rangeQuery("price").lte(40);// lte小于 gte大于
    SearchResponse sr=srb.setQuery(QueryBuilders.boolQuery()
                                   .must(queryBuilder)
                                   .filter(queryBuilder2))
        .execute()
        .actionGet();
    SearchHits hits=sr.getHits();
    for(SearchHit hit:hits){
        System.out.println(hit.getSourceAsString());
    }
}
