如何在文档中搜索任何值

Question

我想搜索所有存在的值，而无需显式指定键。这种类型的模式可能吗？如果是这样，我该如何编写查询。我试图用其他引用编写查询，但是如果不为每个引用指定键，就无法编写查询。

const pschema = new Schema({
  user: {
    type: Schema.Types.ObjectId, // combine by id
    ref: "users" //existing model reference
  },
  company: {
    empNo: {
      type: Number,
      required: true
    },
    status: {
      type: String,
      required: true
    },...
  },
  personal: {
    gender: {
      type: String
    },
    dob: {
      type: Date
    },...
  },
  skills: {
    type: [String],
    required: true
  },
  experience: [
    {
      title: {
        type: String,
        required: true
      },
      company: {
        type: String,
        required: true
      },
      location: {
        type: String
      }...
    }
  ],
  education: [
    {
      school: {
        type: String,
        required: true
      },
      degree: {
        type: String,
        required: true
      },
      specialization: {
        type: String
      },..
    }
  ],
  social: {
    twitter: {
      type: String
    },
    facebook: {
      type: String
    },
    linkedin: {
      type: String
    },...
  }
});

例如：如果我给linkedin网址提供搜索，则应该在社交linkedin中搜索；如果我给c，则应该输入技能数组中的搜索
