Javascript 查找哪个字段'；集合中的大小大于20000（mongodb）

我的收藏中有这个文档，我需要找到像这样的所有文档中哪个字段的值大于20000。集合的某些字段正在动态更改

db.doors.find(
  {
    "doorseller": "e0asda9a0fqqf7-f0asdas66-48c4-bfe5-ssss", 
    "good.Derinlik.value" : {$exists:true}, 
     $where: "this.good.Derinlik.value.length > 20000" 
  }
)

这是可行的，但我还需要检查其他字段；但是，我不想为它们中的每一个手动编写查询。有什么办法吗？ 例如，我想检查

-runningStatus
-good.renkodu.value

这些文件都在改变，它们的名字都在改变

这是示例文档

        "doorseller" : "e0asda9a0fqqf7-f0asdas66-48c4-bfe5-ssss",

我可以建议您在DBshell中运行简单的javascript代码：

var keys = [];

db.doors.find({}).forEach(function(doc){
    for (var key in doc){ 
      if(typeof(doc[key]) == 'number' && doc[key] > 20000){
       keys.push({"doc.id": doc._id, "key":key, "value":doc[key]});
      }
    }
});
print(keys);   // prints all the results

注意事项：

当您有许多文档时，doc.id是特定文档的标识符

当值位于相同深度（级别0）时，上面的脚本效果良好

这不是数字。我想检查一下字符串的长度或其他什么。而且它们不在同一水平：(
