I created a mapping

https://192.168.56.128:9200/article
{
    "settings" : {
        "analysis" : {
            "analyzer" : {
                "custom_analyzer" : {
                    "tokenizer" : "standard",
                    "filter" : [ "lowercase", "ru_RU" ],
                    "char_filter" : [ 
                        "html_strip"
                    ]
                }
            },
            "filter" : {
                "ru_RU" : {
                    "type" : "hunspell",
                    "locale" : "ru_RU"
                }
            }
        }
    },
    "mappings" : { 
        "properties" : { 
            "message" : { 
               "type" : "text",
               "analyzer" : "custom_analyzer"
            }
        }
    }
}

But when I try to
https://192.168.56.128:9200/article/_analyze

I get
{
“error”: “no handler found for uri [/article/_analyze ] and method [POST]”
}

How Do I properly test analyzers?
