Hi guys,  
I'm wondering what's the best implementation of an index which stores XML data, written and processed by logstash, with unbounded elements.  
Here is a simple example schema:

> \<xs:complexType name="root"\>  
> xs:sequence  
> \<xs:element name="header\_element" type="header\_element\_type" /\>  
> \<xs:element name="body\_element" type="body\_element\_type" maxOccurs="unbounded" /\>  
> \</xs:sequence\>   
> \</xs:complexType\>  
> \<xs:complexType name="header\_element\_type"\>  
> xs:sequence  
> \<xs:element name="trx\_data" type="string" /\>  
> \<xs:element name="name" type="string" /\>  
> \</xs:sequence\>  
> \</xs:complexType\>  
> \<xs:complexType name="body\_element\_type"\>  
> xs:sequence  
> \<xs:element name="general\_data" type="string" /\>  
> \<xs:element name="school\_data" type="integer" /\>  
> \</xs:sequence\>  
> \</xs:complexType\> Blockquote

The first idea was using an index template as best practise, but then I was told that body\_element can occurs many times ☹  
What I would like to do is to avoid writting data of a single XML payload in multiple docs (n per n body + 1 per header and using an id field to relate them) because I suspect this will stress too much ES when doing data analytics.

Any idea or suggestion will be extremely appreciated.  
Thank you guys!

Andrea
