elasticsearch - Elastic Search for Long类型上的嵌套查询(ES 5.0.4)

这是我关于堆栈溢出的第一个问题，请原谅我的错误。以后我会改进它们。
我也是Elastic Search的新手。好的，我正在尝试在 flex 搜索(5.0.4)中进行精确匹配。该请求将返回存在的所有文档，而不是进行完全匹配。
不知道这种行为。

这是映射

{
   "properties":{
      "debug_urls":{
         "properties":{
            "characteristics":{
               "type":"text",
               "fields":{
                  "keyword":{
                     "type":"keyword",
                     "ignore_above":256
                  }
               }
            },
            "url_id":{
               "type":"long"
            }
         },
         "type":"nested"
      },
      "scanId":{
         "type":"text",
         "fields":{
            "keyword":{
               "type":"keyword",
               "ignore_above":256
            }
         }
      }
   }
}

这是我的要求。

{
    "query": {
        "nested": {
           "path": "debug_urls",
           "query": {
               "match": {
                  "debug_urls.url_id": 1
               }
           }
        }
    }
}

最佳答案

如果只想查看符合条件的嵌套文档，则可以利用nested inner_hits :

{
    "_source":["scan_id"],                     <--- add this line
    "query": {
        "nested": {
           "path": "debug_urls",
           "query": {
               "match": {
                  "debug_urls.url_id": 1
               }
           },
           "inner_hits": {}                    <--- add this line
        }
    }
}
