XFES\Elasticsearch\RequestException: Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default. Please use a keyword field instead. Alternatively, set fielddata=true on [field_choice_single] in order to load field data by uninverting the inverted index. Note that this can use significant memory. src/addons/XFES/Elasticsearch/Api.php:424
