I am using highlighting(fvh) in the elasticsearch to highlight the keyword.  
When I do a search with keyword 5-2011, it produces the result with the keyword 005-2011 but it doesn't highlight the keyword.  
My query to highlight is

```auto
 {
                             "type": "fvh",
                             "pre_tags": ["<em>"],
                             "post_tags": ["</em>"],
                             "number_of_fragments": 100,
                             "fragment_size": 50,
                            "fields": { "*": {} }
}

```

**Elasticsearch version:** 7.4.0  
**Actual behavior:**  
it doesn't return highlight for the keyword(5-2011)

**expected behavior:**

> 00"\< em \>5-2011\</ em \>

**search query:** [{'size': 10, 'query': {'bool': {'must': [{'bool': {'should': [{'bool': {'should' - Pastebin.com](https://pastebin.com/gBp5wfE4)
