mongodb $ lookup将ObjectID嵌套在本地数组中，然后按位置$ near对数组进行排序

Question

工具型号

{
  name: "this is a tool",
  hospitals: [
    "5f45ea0a3e81a01abfe4b370",
    "5f45ea0a3e81a01abfe4b371",
  ]
}

医院模型

{
  name: "this is a hospital",
  location: [
   type: "Point",
   coordinates: [130.0, 30.0]
  ]
}

我所需要做的只是按ID查找工具，然后填充医院，然后按位置对医院进行排序。
