H All,

We have a bunch fields on index and we have a template defined for this index to define the mapping for these fields. However, we are adding few dynamic fields whose names prefix with a constant and name of the other fields.  
For example, in template if we have fields like first\_name, last\_name, sometimes dynamically we are adding op\_first\_name, op\_last\_name.. etc. Is there a way to specify mapping for these dynamic fields so that they inherit mapping from original fields. Such as op\_first\_name mapping is same as first\_name.. etch without explicitly specifying for each and every field.

We are on ES 6.5

Thank you  
Ashok
