I'm using RabbitMQ plugin of Logstash to pull from RabbitMQ and push to Elasticsearch using this pipeline:

```auto
input {
    rabbitmq {
        queue => "Elasticsearch_Queue"
        host => "rabbitmq"
        exchange => "my_event_bus"
        key => "SomeIntegrationEvent" # How to define multiple keys?
    }
}
output {
    elasticsearch {
        hosts => ["elasticsearch:9200"]
    }
    stdout { codec => rubydebug }
}

```

It works fine and creates a queue named `Elasticsearch_Queue` and binds to `my_event_bus` exchange using routing\_key `SomeIntegrationEvent` .

I need to **subscribe to multiple events** but there is no clear solution on the [plugin docs](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-rabbitmq.html#plugins-inputs-rabbitmq-key).

The value key is a string and you cannot use the syntax like ["key1","key2"]  
Try the following way:

```
input {
    rabbitmq {
        queue => "Elasticsearch_Queue"
        host => "rabbitmq"
        exchange => "my_event_bus"
        key => "SomeIntegrationEvent1" 
    }
    rabbitmq {
        queue => "Elasticsearch_Queue"
        host => "rabbitmq"
        exchange => "my_event_bus"
        key => "SomeIntegrationEvent2" 
    }
}
```
