Why is not possible to remove completly a mapping field ? (I would like to change a field type to boolean to string, I have removed this field, but I cannot change the mapping field type despite there is no data for this field :/)
I am using update_by_query for reindexing, because I want to stay on the same index.
I know https://www.elastic.co/guide/en/elasticsearch/reference/2.3/indices-delete-mapping.html has been removed, I hope there is a way to achieve it.
A big thanks !
