Javascript 如何修复此sql到mongo转换的展开部分？

我一直在尝试将SQL转换为Mongo，我也尝试过自己尝试，但结果似乎发生了变化（可能是解围的原因），非常感谢您的帮助

也不完全确定如何在mongo中编写order by之后的部分代码。文档似乎没有任何帮助

select u.id, flair, "displayName", date_part('year', age(birthday)) "age", bio, "codeImgIds", "photoUrl"
         from "user" u
         left join view v on v."viewerId" = $1 and u.id = v."targetId"
         left join view v2 on $2 = v2."targetId" and v2.liked = true and u.id = v2."viewerId"
         where
         v is null
         and u.id != $3
         ${user.goal === "love" ? user : friendWhere}
         and array_length("codeImgIds", 1) >= 1
         and "shadowBanned" != true
         order by
           random()
           - (case
               when (v2 is not null)
               then .2
               else -least(current_timestamp::date - u."lastSwipe"::date, 14) / 14.0
             end)
           - LEAST(u."numSwipesToday", 20) / 20.0
         limit 20;
         `,
         user.goal === "love" ? loveParams : friendParams

我的尝试

const result = await user.findById(req.user.data._id);

user
    .aggregate([
      {
        $lookup: {
          from: "views",
          pipeline: [{ $match: { viewerId: { $ne: _id } } }],
          as: "v",
        },
      },
      { $unwind: "$v" },
      {
        $lookup: {
          from: "views",
          let: { targetId: _id, liked: true },
          pipeline: [{ $match: { liked: true } }],
          as: "v2",
        },
      },
      { $unwind: "$v2" },
      {
        $match: {
          $and: [
            { _id: { $nin: [req.user.data._id, v2.viewerId] } },
            { goal: result.goal },
            { shadowBanned: false },
            { genderToShow: result.genderToShow },
          ],
        },
      },
    ])
