Stopwords keep existing after indexing data

Elastic Stack Elasticsearch

Hi,

I'm new on dealing with stopwords and even though I've read and tried what has been written on the page about "Using Stopwords", I can't get it working.

I have a csv-file containing two columns: email_category and email_content. I'm indexing this file with Logstash and its csv-filter. Before I index it with Logstash I have written a mapping in Sense and it looks like this:

PUT /emails
{
    "settings" : {
        "analysis": {
            "analyzer": {
                "my_analyzer": { 
                    "type": "dutch",
                    "stopwords": "_none_"

                }
            }
        }
    },
    "mappings" : {
        "emails" : {
            "properties" : {
                "email_category" : { 
                    "type" : "string",
                    "index": "not_analyzed"
                },
                "email_content" : { 
                    "type" : "string",
                    "index": "analyzed",
                    "analyzer": "my_analyzer"
                }
            }
        }
    }
 }

Any ideas why the content keeps having dutch stopwords? It is not removing anything.

Never mind. I did not know that stopwords remain visible when you are in "Discover" in Kibana but when you are visualizing in Kibana then those words are not being counted.
