Hi, our mappings contain **keyword** field (type is keyword) for all properties which have type "text". This keyword is then used for term queries, sorting, aggregations, ... But sorting doesn't work well for some languages. Is it safe to change type from keyword to **icu\_collation\_keyword**? I tried some queries and it seems to me that results are the same and sorting works well. Could you please describe differences between type of keyword and icu\_collation\_keyword?

Version of ES: 6.7.2

Thank you!  
Dan
