Hi all !
I want to set up a case-insensitive sort order in an aggregation, made from a keyword field.
Apparently, it wasn't possible with ES 5.2 (see Keyword type: aggregation case insensitive).
I tried to deal with it on ES 6.4, but without success, using "icu_collation_keyword" subfield and "bucket sort aggregation".
Is it at least possible, in this version (6.4) ?
Has anyone already implemented it ?
If the answer is yes, so how ?
