Mongoose MongoDB Atlas按参考文档字段搜索词搜索

我知道如何通过名称和给定的买家ID以及已知的/

匹配的

供应商名称来搜索订单 例如：

（使用猫鼬ODM）

但是，我希望能够利用MongoDB Atlas搜索：

• 搜索所有订单
• 给定一个

  买方ID

• 其中搜索词-可能不是完全匹配-是供应商名称
• 如果买方和供应商通过引用ID嵌套在订单上：

具有

顺序

模式：

const orderSchema = new mongoose.Schema({
  name: {
    type: String,
    minlength: 2,
    maxlength: 255,
  },
  buyer: { type: ObjectId, ref: 'Buyer' },
  supplier: { type: ObjectId, ref: 'Supplier' },
});

const buyerSchema = new mongoose.Schema({
  name: {
    type: String,
  },
  ...
});

const supplierSchema = new mongoose.Schema({
  name: {
    type: String,
  },
  ...
});

买方

模式：

const orderSchema = new mongoose.Schema({
  name: {
    type: String,
    minlength: 2,
    maxlength: 255,
  },
  buyer: { type: ObjectId, ref: 'Buyer' },
  supplier: { type: ObjectId, ref: 'Supplier' },
});

const buyerSchema = new mongoose.Schema({
  name: {
    type: String,
  },
  ...
});

const supplierSchema = new mongoose.Schema({
  name: {
    type: String,
  },
  ...
});

供应商

模式：

const orderSchema = new mongoose.Schema({
  name: {
    type: String,
    minlength: 2,
    maxlength: 255,
  },
  buyer: { type: ObjectId, ref: 'Buyer' },
  supplier: { type: ObjectId, ref: 'Supplier' },
});

const buyerSchema = new mongoose.Schema({
  name: {
    type: String,
  },
  ...
});

const supplierSchema = new mongoose.Schema({
  name: {
    type: String,
  },
  ...
});

我已经通过以下内容实现了所需的结果，但它没有使用Atlas搜索，因此我希望您能提供更多帮助

const order = await Order.aggregate([
      { $unwind: '$supplier' },
      {
        $lookup: {
          from: 'suppliers',
          localField: 'supplier',
          foreignField: '_id',
          as: 'suppliers',
        },
      },
      {
        $match: {
          buyer: mongoose.Types.ObjectId('5e19a594c86e72017debf9dc'),
          'suppliers.name': new RegExp('^' + supplierName, 'i'),
        },
      },
    ]);

这应该可以使用，并且在

$search

中：

const order = await Order.aggregate([
{ $search: {
    compound: {
        must: [ 
            { text: { query: "SEARCH TERM", path: "name"}}, 
            { equals: { path: "buyer", value: ObjectId("5e19a594c86e72017debf9dc") }} 
        ]
    }
}}])

如果不想影响评分，也可以将equals查询移动到filter子句
