Noob here, so don't judge too hard. 😉

However, I am wanting to find out if it's possible to have an output as such that's looking for specific tags and sending those messages to the windows\* index but if they don't match they go to a pipeline\* index. Is that possible???

```auto
       }
    output {
            if "NxLog","Windows Event" in [tags] {
                elasticsearch {
                hosts => "${ELASTICSEARCH_HOST_AND_PORT:elasticsearch.:9200}"
                index => "windowsevent-%{+YYYY.MM.dd}"
                }}
            else {
                elasticsearch {
                hosts => "${ELASTICSEARCH_HOST_AND_PORT:elasticsearch.:9200}"
                index => "pipeline-%{+YYYY.MM.dd}"
            }
    }

```

This can be done using a conditional in the output section, but I think it would need to be

```
if "NxLog" in [tags] or "Windows Event" in [tags] { ...

```
