Hi,  
I have a question:  
can the parent and the child have the same field name??

Example:

```
parentDoc: childDoc :  
 {name: ********, {name:******
    age: **********age:*******
    salary: ********schoolname:**********
  } activities: **************
                                     }

```

Thank you!

Yes they can, they are separate docs after all.
