mongodb - 我们如何在 mongodb 中使用 near 计算距离

Question

请参考以下链接：mongodb 中的 next。我想计算我给出的坐标与文档中存在的坐标之间的距离。我有以下查询

db.hotels.aggregate([
{
    $search: {
      index:'searchIndex', //index name
      compound: {
        must: {
          text: {
            query:'sun',
            path:['name','address.landmark','address.city','address.state','address.country'],
            fuzzy: {
              maxEdits:2,
              prefixLength: 3,
            },
          },
        },
        should: {
            near:{
             origin: {
                type: 'Point',
                coordinates: [-122.45665489904827,37.75118012951178],
             },
            pivot: 1000,
            path: 'location' // how can I calculate distance too here?
          },
        }
      }
    }
  },
  {
      $project: {
          _id: 1,
          name: 1,
          address:1,
          score: { $meta: "searchScore" }
       }
    },
    {$limit:100},
])

我也想用近来显示距离。还是有另一种方法可以计算距离？
