Mongodb yaml中距离的ODM原则

如何在yaml映射文件中添加@Distance？我试过了，但没用

CP\AppBundle\Document\Point:
  type: embeddedDocument
  embedOne:
    address:
      targetDocument: CP\AppBundle\Document\Address
    coordinates:
      targetDocument: CP\AppBundle\Document\Coordinates
  distance: distance
  indexes:
    coordinates:
      keys:
        coordinates: 2d

非常感谢

距离字段需要指定为带有距离参数的浮点：

CP\AppBundle\Document\Point:
  type: embeddedDocument
  embedOne:
    address:
      targetDocument: CP\AppBundle\Document\Address
    coordinates:
      targetDocument: CP\AppBundle\Document\Coordinates
  fields:
    distance:
      type: float
      distance: true
  indexes:
    coordinates:
      keys:
        coordinates: 2d
