Hi,

I have following fields in my event:

```
...
 "stage": [
      "shared",
      "QA",
      "dev_trunk"
    ],
...

```

I want to set a new meta field to to _staging_, if the stage filed contains, QA, dev\_trunk or PreProd.

I have tried with following sniplet:

```
# process the stage
	if [stage] == "Production"
	{
		mutate
		{
			 add_field => { "[@metadata][indexCluster]" => "prod" }
		}
	}
	#elseif [stage] in ["QA", "dev_trunk", "PreProd"]
	elseif "QA" in [stage] or "dev_trunk in [stage] or "PreProd" in [stage]
	{
		mutate
		{
			add_field => { "[@metadata][indexCluster]" => "staging" }
		}
	}
	else
	{
		mutate
		{
			add_field => { "[@metadata][indexCluster]" => "no_stage_defined" }
		}
	}

```

The event above is resulting in "no\_stage\_defined".

How can I correct this?

I am using logstash 5.2.0  
Thanks, Andreas
