Hi,

Is it possible to specify the type and analyzer while adding a new field to  
an existing index?  
Looks like ES identifies automatically the type and uses the default  
analyzer.

Would appropriate your help.

Thanks  
Rahul

You can use Put Mapping API to add new fields with proper mapping before  
the first instance of such field is indexed. See
