Elasticsearch contains query does a fuzzy match instead of like query

**Describe the bug**
When I do a contains search in the cube for an elasticsearch database it creates a fuzziness SQL query

**To Reproduce**
Cube Query
```
{
"filters": [
{
"dimension": "index.message",
"values": [
"viral"
],
"operator": "contains"
}
],
"limit": 1,
"dimensions": [
"index.user_id"
]
}
```

This creates a SQL query like this
```
SELECT
index.user_id index__user_id
FROM
index AS index
WHERE ( MATCH(index.message, 'viral', 'fuzziness=AUTO:1,5')) GROUP BY index.user_id ORDER BY index.user_id ASC LIMIT 1
```

Is there any reason we are not using the LIKE query in this case
If not then can I change it, such that the engine creates a LIKE query when the input cube query has operator as **contains**
