elasticsearch 多条件查询 - 权重查询 

根据得分查询 should

使用得分之前

POST http://192.168.199.126:9200/film/dongzuo/_search/
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "title": "战"
          }
        }
      ]
    }
  }
}

使用得分之后 should

POST http://192.168.199.126:9200/film/dongzuo/_search/
{
  "query": {
    "bool": {
      "must": {
        "match": {
          "title": "战"
        }
      },
      "should": [
        {
          "match": {
            "content": "星球"
          }
        },
        {
          "range": {
            "publishDate": {
              "gte": "2018-01-01"
            }
          }
        }
      ]
    }
  }
}

使用得分查询 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();
        }
    }


/**

     * @throws Exception
     */
@Test
public void searchMutil3()throws Exception{
    SearchRequestBuilder srb=client.prepareSearch("film").setTypes("dongzuo");
    QueryBuilder queryBuilder=QueryBuilders.matchPhraseQuery("title", "战");
    QueryBuilder queryBuilder2=QueryBuilders.matchPhraseQuery("content", "星球");
    // 范围查询 gte方法 不包含小写，gt方法包含小写 即 includeLower=true
    QueryBuilder queryBuilder3=QueryBuilders.rangeQuery("publishDate").gt("2018-01-01");// 范围查询 gt表示大于
    SearchResponse sr=srb.setQuery(QueryBuilders.boolQuery()
                                   .must(queryBuilder)
                                   .should(queryBuilder2)  // 设置权重
                                   .should(queryBuilder3)) // 设置权重
        .execute()
        .actionGet();
    SearchHits hits=sr.getHits();
    for(SearchHit hit:hits){
        System.out.println(hit.getScore()+":"+hit.getSourceAsString());
    }
}
