I have the english stemmer on an analyzer which is used on a field. when I search exact it works fine. when I add ~ it doesnt match anything. ie:

This works

```
{
  "size": 20,
  "query": {
    "query_string": {
      "query": "googles",
      "default_field": "search",
      "default_operator": "and",
      "fuzziness": 1,
      "fuzzy_prefix_length": 1
    }
  }
}

```

this does not work

```
{
  "size": 20,
  "query": {
    "query_string": {
      "query": "googles~",
      "default_field": "search",
      "default_operator": "and",
      "fuzziness": 1,
      "fuzzy_prefix_length": 1
    }
  }
}

```

I've tested the analyzer and I can see its dropping the 'es' from the end to 'googl' on index from stemming.

I'm guessing on search the stemming is not being applied to the term as 'googles~' is further than 1 fuzziness from the indexed 'googl'. 'google~' matches.

I've read [here](https://www.elastic.co/guide/en/elasticsearch/reference/5.5/query-dsl-query-string-query.html#_wildcards) that stemming is excluded on wildcards but it doesnt say anything on fuzziness.

Is this expected behavior? if so what would be the alternative? the reason I use query\_string is so I can control which words can be fuzzy matched. I've tested the 'match' query with fuzziness and that works as expected.

Thanks  
Ben
