It's not supported yet in the HLClient but it's trivial to implement. See [https://github.com/dadoonet/fscrawler/blob/master/elasticsearch-client/src/main/java/fr/pilato/elasticsearch/crawler/fs/client/ElasticsearchClient.java#L134](https://github.com/dadoonet/fscrawler/blob/master/elasticsearch-client/src/main/java/fr/pilato/elasticsearch/crawler/fs/client/ElasticsearchClient.java#L134)
