Hi,

we have this tested EPL code that we want to modify: instead of matching an alarm event with type = {string} we would like to match the alarm event if the type contains (or includes) a particular string:

## existing EPL code

on all Alarm(type=ALARM\_IN\_TYPE, status=“ACTIVE”) as a1 → Alarm(type=ALARM\_OUT\_TYPE, status=“ACTIVE”) as a2 {

---

Hi,

Unfortuenately we can’t filter the events on the type that contains a string or starts with a string.  
Instead of it, we can simply do as follows ,

```auto
on all Alarm(status=“ACTIVE”) as a1 {
          if a1.type.contains("subString") {....}
}

```

Thank,
