**Data** :

```
Doc 1:
       field_a : ["A", "B", 'C", "D", "E"]

Doc 2:
       field_a : ["A", "D", "G", "Z", "Y"]

Doc 3:
       field_a : ["F", "W", 'C"]

Doc 4:
       field_a : ["A", "B", 'C", "D", "E", "Z", "Y"]

Doc 5:
       field_a : ["A", "B", "C"]

```

PS: `field_a` is of _Keyword_ type.

**Query** :

`terms: ["A", "B", "C", "D", "E"]`

**Required Response** :

```
Doc 1: 5
Doc 2: 2
Doc 3: 1
Doc 4: 5
Doc 5: 3

```

Require the required response. It will be perfect if there is any way to generate **Custom Score Function** to get the same.
