Elasticsearch在排序geo_query时忽略must_not

Question

此查询返回uuid子句中带有must_not的第一条记录。

当删除排序时，带有uuid的文档不在列表中，但我得到随机结果，我希望它们按位置asc排序（似乎包括）

使用6.0 api版本。

{
"query": {
    "bool": {
        "filter": {
          "geo_distance": {
            "location": {
              "lat": -33,
              "lon": 151
           },
            "distance": "100km"
          }
        },
        "must_not": {
            "term": {
            "uuid": "a3330c1a-8a24-4c7f-ad97-16ac5bd73e3f"
          }
        }
      }
    },
    "sort": [
     {
        "_geo_distance": {
          "location": {
            "lat": -33,
            "lon": 151
          },
          "order": "asc",
          "unit": "km",
          "mode": "min",
          "distance_type": "arc"
        }
      }
    ],
    "size": 10
}

第一个结果

{
"took": 17,
"timed_out": false,
"_shards": {
  "total": 5,
  "successful": 5,
  "skipped": 0,
  "failed": 0
},
"hits": {
  "total": 1504,
  "max_score": null,
  "hits": [
    {
      "_index": "myindex",
      "_type": "mytype",
      "_id": "a3330c1a-8a24-4c7f-ad97-16ac5bd73e3f",
      "_score": null,
      "_source": {
        "latitude": -33,
        "longitude": 151,
        "uuid": "a3330c1a-8a24-4c7f-ad97-16ac5bd73e3f",
        "location": [
          151,
          -33
        ]
      },
      "sort": [
        0
      ]
    }
  ]

Answer 1

您的 uuid 字段是否为文字或关键字？查看Why doesn’t the term query match my document部分。

有两种解决方案：

1）将您的查询更改为：

 "must_not": {
        "term": {
            "uuid.keyword": "a3330c1a-8a24-4c7f-ad97-16ac5bd73e3f"
      }
    }

或2）将您的uuid字段定义为关键字而不是文字：

PUT myindex
{
  "mappings": {
     "mytype": {
        "properties": {
           "uuid": {
              "type":  "keyword"
            }
         }
     }
  }
 }
