Hello there, I'm new with all elasticsearch stack so it may sound easy and simple task, but I can't find information on how to achieve what I want.

I'm using SQS input to the Logstash and output to the elasticsearch.

So there is an example of what do I expect.

Input:

```
{
     "contacts": ["1", "2", "3", "4"],
     "property": "something",
     "data": "15489",
     "code": "871111"
}

```

Output (4 separate documents with all fields cloned expect "contacts" changes to -\> "contact" per each value in array):

```
{
     "contact": "1",
     "property": "something",
     "data": "15489",
     "code": "871111"
}
{
     "contact": "2",
     "property": "something",
     "data": "15489",
     "code": "871111"
}
{
     "contact": "3",
     "property": "something",
     "data": "15489",
     "code": "871111"
}
{
     "contact": "4",
     "property": "something",
     "data": "15489",
     "code": "871111"
}

```

Any ideas? Thanks

You can split an array into multiple events using a [split](https://www.elastic.co/guide/en/logstash/current/plugins-filters-split.html) filter.

Thanks @Badger!

Yes it worked, should have researched better on this one.

There is a solution:

```
filter {
        split {
                field => "contacts"
                target => "contact"
                remove_field => ["contacts"]
        }
}
```
