Suppose we have a documents of people with their name and array of aliases like this:

```auto
{
   name: "Christian",
   aliases: ["נוצרי", "کریستیان"]
}

```

Suppose I have a document with 10 aliases and another one with 2 aliases  
but both of them contains alias with value `کریستیان`.

The `length of field (dl)` for the first document is bigger than the second document  
so the `term frequency (tf)` of the first document gets lower than the second one  
and the score of the document with less aliases is bigger than another.

Sometimes I want to add more aliases for person in different languages and different forms because he/she is more famous but it causes to get lower score in results. I want to somehow take `length of the aliases field` out of my query's calculation.

Can you perhaps add the alias match as a [filter clause](https://www.elastic.co/guide/en/elasticsearch/reference/7.7/query-dsl-bool-query.html) to avoid it affecting scoring at all?
