My data structure is

```auto
{
   eventData :{
      level:6,
     class:beginner
   }
}

```

or

```auto
{
   eventData :{
      level:6,
     money:1000
   }
}

```

Please tell me how to mapping on this structure.  
`eventData` have various constructure so we cannot make mapping when we make index.

Thank you.
