Right now, I'm able to create a working stopword filter in the following way.

```auto
company_name_stopword = ["inc","corp"]
_company_name_stopword_filter = dsl.token_filter("_company_name_stopword_filter",
    type="stop",
    ignore_case = "true",
    stopwords=company_name_stopword
)

_tag_analyzer = dsl.analyzer('tag_analyzer',
    tokenizer="whitespace",
    filter=["lowercase",_company_name_stopword_filter] 
)

response = _tag_analyzer.simulate(
    text = 'Apple Inc',
    using = localhost)
print([t.token for t in response.tokens])

```

The objective is to remove from `text` input and string in the list `company_name_stopword`.

However, the index I'm using, uses `tokenizer="keyword"` instead of `tokenizer="whitespace"`.

Is it possible to create this filter with a keyword tokenizer? I can't change the tokenizer of the index without incurring into potential large behavioural/performance changes...
