I would like to have a field that consists of values of other fields. E.g if a document has 2 fields; name and age, then there will be automatically created a new multivalued field that consists of these two formentioned fields.

Example:  
"name" : John  
"age" : 20  
"combo" : [John, 20]

How can we do this in Elasticsearch? Is it possible to configure in any way to have this behaviour?
