I have the following document structure:  
  
**//nested type**  
**//nested type**  
...  
  
  
...  
  
  
...

But if in document I have only one instance of EgnaElement, search operation returns EgnaElement just as object but not array. Like this:  
...  
EgnaElement{  
EgetElement[  
...  
]  
}  
...

May be Elasticsearch has some setting to prevent this unnecessary convertion
