如何同时使用Elasticsearch的geo_point和geo_shape类型？

Question

这是我们的文件:

{
    "geometry" : {
        "type" : "Point",
        "coordinates" : [ -87.662682, 41.843014 ]
    }
}

我们希望做一个geo_shape与搜索_geo_distance排序,都对同一geometry领域.前者需要geo_shape类型,而后者需要geo_point.

这两个索引单独成功,但不能一起成功:

"geometry": {
    "type": "geo_shape"
}

和

"geometry": {
    "properties": {
        "coordinates": {
            "type": "geo_point"
        }
    }
},

到目前为止,我们尝试过这些并且失败了:

"geometry": {
    "type": "geo_shape"
},
"geometry.coordinates": {
    "type": "geo_point"
},

也

"geometry": {
    "copy_to": "geometryShape",
    "type": "geo_shape"
},
"geometryShape": {
    "properties": {
        "coordinates": {
            "type": "geo_point"
        }
    }
}

也

"geometry": {
    "copy_to": "geometryShape",
    "properties": {
        "coordinates": {
            "type": "geo_point"
        }
    }
},
"geometryShape": {
    "type": "geo_shape"
}

有关如何正确创建此索引的任何想法？

如果启用了脚本，那么您可以通过在映射中指定转换来实现它

会看起来像这样：

put test/test_type/_mapping
{
   "transform": {
      "script": "if (ctx._source['geometry']['coordinates']) ctx._source['test'] = ctx._source['geometry']['coordinates']",
      "lang": "groovy"
   },
   "properties": {
      "geometry": {
         "type": "geo_shape"
      },
      "coordinates": {
         "type": "geo_point"
      }
   }
}
