针对嵌套文档的Elasticsearch Geo形状搜索

Question

我希望能够使用geo_shape过滤器（其中geojson是嵌套的子文档）搜索文档，并且只检索与地理过滤器匹配的1子文档（而不是整个文档）。我认为文档（特别是嵌套对象类型和嵌套查询/过滤器文档）表明这可以使用join：false。出于某种原因，我无法让它工作，我确信这是用户错误或缺乏理解。

在ES 90.5及以下是一个有效的例子。

有人能指出我正确的方向吗？

清除卡组并创建新索引

curl -XDELETE http://es_server.com:9200/test

{"ok":true,"acknowledged":true}

curl -XPUT  http://es_server.com:9200/test

{"ok":true,"acknowledged":true}

设置新映射

curl -XPUT http://es_server.com:9200/test/testtype/_mapping -d '{
  "testtype": {
    "properties": {
      "entities": {
        "type": "nested",

          }
        }
      }
    }

{"ok":true,"acknowledged":true}

索引新文档
