Question

我正在尝试从填充的模型中搜索商品名称。我的模型如下：

     export interface IIddwModel extends Document {
      problemType: Schema.Types.ObjectId | IProblemTypeModel;
      commonName: Schema.Types.ObjectId | ICommonNameModel;
      scientificName: Schema.Types.ObjectId | IScientificNameModel;
      causalAgentType: Schema.Types.ObjectId |ICausalAgentTypeModel;
      }

   const iddwSchema = new Schema(
    {
       problemType: {
       type: Schema.Types.ObjectId,
       ref: "ProblemType",
       required: true
    },
       commonName: {
       type: Schema.Types.ObjectId,
       ref: "CommonName",
       required: true
    },
       scientificName: {
       type: Schema.Types.ObjectId,
       ref: "ScientificName",
       required: true
    },
       causalAgentType: {
       type: Schema.Types.ObjectId,
       ref: "CausalAgent",
       required: true
    }
  },
  {
     timestamps: true
  }
  );
  iddwSchema.index({ "$**": "text" });

我的控制器是

    Iddw.find()
        .populate([
          {
            path: "problemType",
            model: ProblemType,
          },
          {
            path: "commonName",
            model: CommonName
          },
          {
            path: "scientificName",
            model: ScientificName
          },
          {
            path: "causalAgentType",
            model: CausalAgentType
          }
        ])
        .then(iddws => {
          return res.status(200).json({
            iddws: iddws
          });
        })
        .catch((error: WriteError) => {
          return res.status(500).json({
            error: error.code
          });
        });

如何从填充的字段进行搜索？我尝试过

    if (req.query.search) {
       query.$text = {
       $search: req.query.search
    }; 
   Iddw.find(query)
   .then(() => {}

但是它只能从IDDW模型一部分的字符串字段中搜索，而不能从问题字段，commonName，scientificName等填充文件中搜索。如何从这些填充字段中搜索？
