I have a problem with keyword type:  
can i aggregate a a file with a keyword type wihout losing the case and sorting case insensitive?

Using the normalizer and lowercase filter lose the the case.  
using the text type must enable fielddata that can consume a lot of heap space, especially when loading high cardinality

Elasticsearch version: 5..2

not sure I understand, why do you use the normalizer if you don't want to do case folding?
