Hello guys,

I'm trying to reindex to add an English stopwords filter, but after running a simple terms aggregation, words like "the" or "a" are still on top of the list. What might be the problem?

This is my mapping:

```
PUT myIndex
    {
        "order": 0,
        "settings": {
            "index": {
                "analysis": {
                    "analyzer": {
                        "my_analyzer": {
                            "filter": [
                                "lowercase",
                                "trim",
                                "stemmer_filter",
                                "stopwords_filter",
                                "reverse"
                            ],
                            "type": "custom",
                            "tokenizer": "standard"
                        }
                    },
                    "filter": {
                      "stopwords_filter": {
                        "type": "stop",
                        "stopwords": "_english_"
                      },
                      "stemmer_filter": {

                      }

                },
                "number_of_shards": "1",

            }
        },

                                "analyzer": "my_analyzer",
                                "type": "text"
                            },
                            "raw": {
                              "type": "keyword"
                            }
                        }
                    }
                }
            }

You'd have to aggregate on the `words.reverse` field, since that's the one that uses your analyzer.
