Hello!

I'm trying to parse CheckPoint log which contains duplicated keys but with different values.  
For example `... match_id:"555"; match_id:"777"; ...`

When I use kv plugin

```auto
kv {
  source => "message"
  field_split => ";"
  value_split => ":"
  trim_key => " "
}

```

I get something like `match_id: 555, 777`

Is it possible to get result as

```auto
match_id.1: 555
match_id.2: 777

```

and then rename these fields to

```auto
match.id.1: 555
match.id.2: 777

```

?

Thank you 🙂

Use a ruby filter. Something like [this](https://discuss.elastic.co/t/parsing-an-array-in-ruby/121254/2).

@Badger thank you for your advice  
I've add this code to the filter

```auto
ruby {
    code => '
      event.get("match_id").each_with_index { |x, i| event.set( "[match][id][#{i}]", x) }
      '
  }

```

And what I see in Kibana

```auto
match.id.0 1970-01-01T00:00:00.555Z
match.id.1 1970-01-01T00:00:00.777Z

```

What could be the problem?
