elasticsearch - Elasticsearch:REST API有效，但Java对应无效

Question

我在Elastic Search中有一个文档:

{
   "accountGroupId":1000,
   "name":"Elastic Burgers",
   "capacity":33,
   "startTime":1391604480000,
   "address":{
      "streetName":"Rua Carlos Petit",
      "streetNumber":"111",
      "complement":"",
      "neighborhood":"Vila Mariana",
      "city":"São Paulo",
      "state":"SP",
      "country":"Brasil",
      "zip":"04110000",
      "position":{
         "latitude":-23.5845048,
         "longitude":-46.6358975
      },
      "accountGroupId":1000,
      "status":[

      ],
      "id":1000,
      "createTime":1391010548111,
      "updateTime":1391010548111
   },
   "flyerUrl":"/assets/images/placeholder-merchant.png",
   "backgroundImageUrl":"/assets/images/placeholder-merchant.png",
   "onSaleStartTime":1391604480000,
   "onSaleEndTime":1392990480000,
   "description":"Lorem Ipsum",
   "eventCategoryId":1000,
   "deleted":false,
   "installmentId":100,
   "feeId":101,
   "restricted":false,
   "venueAccountGroupId":15,
   "updateTime":1391691790113,
   "createTime":1391691790113,
   "id":1002,
   "venue":"Acme, Inc.",
   "category":"Festa Faculdade"
}

此REST查询返回文档:

curl -XGET 'http://localhost:9200/paguemob/events/_search' -d '{
    "query": {
        "multi_match" : {
            "query" : "festa de faculdade",
            "fields" : ["name", "address.city", "venue", "category", "description"]
        }    
    }
}'

但是，如果我通过Java API运行等效查询，则结果为空:

client
  .prepareSearch(index)
  .setQuery(multiMatchQuery("festa de faculdade", "name", "address.city", "venue", "category", "description"))
  .setSize(200)
  .execute()
  .actionGet()
  .getHits

我究竟做错了什么？

Answer 1

看一些ES test code，我看到除了multiMatchQuery本身，他们还将OR设置为运算符(我假设这是默认值)，并将useDisMax设置为false，并设置type。

   searchResponse = client().prepareSearch("test")
   .setQuery(multiMatchQuery("marvel hero captain america", "full_name", "first_name", "last_name", "category")
   .operator(MatchQueryBuilder.Operator.OR).useDisMax(false).type(type)).get();

我想知道其中之一是否有用？

另外，您的示例可能不会显示它，但是您是否正确访问Java中的点击结果数组？

searchResponse.getHits().hits()[0]
