I want to stop all words from the root word "expect", for example, expected, expecting, expectation all shall be stopped.

Here is my mapping.  
PUT /words\_v1  
{  
"settings": {  
"analysis": {  
"analyzer": {  
"extended\_english\_analyzer": {  
"type": "english",  
"stopwords": ["expect"]  
}  
}  
}  
},  
"mappings": {  
"words":{  
"properties": {  
"english": {  
"type": "text",  
"analyzer": "extended\_english\_analyzer",  
"fielddata": true  
}  
}  
}  
}  
}

Then I test it

```
GET /words_v1/_analyze?analyzer=extended_english_analyzer
{"text": "expected expecting"}

```

The result is  
{  
"tokens": [  
{  
"token": "expect",  
"start\_offset": 0,  
"end\_offset": 8,  
"type": "",  
"position": 0  
},  
{  
"token": "expect",  
"start\_offset": 9,  
"end\_offset": 18,  
"type": "",  
"position": 1  
}  
]  
}

You can see "expected" and "expecting" are still tokenized. I want they all be stopped.
