Hi Yoann,

I downloaded an ran the hibernate test case.

I finally found out that if I remove the cluster.name conf line from my elasticsearch.yml file, then the mapping with the analyzer is correctly applied, it's because a new index is created in that case.

Replacing:

...elasticsearch.index_management_strategy: CREATE

by

...elasticsearch.index_management_strategy: RECREATE_DELETE

solved the issue.

Thanks!
