ICUCollationKeyword field (https://www.elastic.co/guide/en/elasticsearch/plugins/current/analysis-icu-collation-keyword-field.html) is great for sorting field. But for the moment it has a major drawback since it cannot take the
ignore_above parameter proposed by Keyword field type (https://www.elastic.co/guide/en/elasticsearch/reference/current/ignore-above.html).
Could it be possible to add this option in a future release ?
With best regards,
