ElasticSearch 上的 Long 类型嵌套查询 (ES 5.0.4)

Question

This is my first question on Stack overflow , please excuse me for the mistakes. I will improve on them in the future. I am new to Elastic Search too. Okay so I am trying to do a exact match in elastic search (5.0.4). Instead of doing an exact match, the request returns all the documents present. Not sure of this behavior.

Here is the mapping

{
   "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
            }
         }
      }
   }
}

This is my request.

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

The response received,

   "took":1,
   "timed_out":false,
   "_shards":{
      "total":5,
      "successful":5,
      "failed":0

If you only want to see the nested documents that match the criteria, you can leverage 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
        }
    }
}
