I just followed the toturial of kuromoji plugin, and tried to use the demo to check if it works. However, when I was trying to create an index using kuromoji\_tokenizer, it cannot be found. (I have restart Elasticsearch after installing the plugin) Here is the code and output.

/elasticsearch-6.2.4$ curl -X PUT "localhost:9200/kuromoji\_sample" -H 'Content-Type: application/json' -d'
