I'm using elapsed plugin.

I have start event, and end event.

```
  if [trigger_status] == "PROBLEM" {
       mutate{ add_tag => ["taskStarted"]}
  }
  if [trigger_status] == "OK" {
       mutate{ add_tag => ["taskTerminated"]}
  }

   elapsed {
       start_tag => "taskStarted"
       end_tag => "taskTerminated"
       unique_id_field => "trigger_id"
   }

```

Is it possible to add TAG at start event when end event get match?  
maybe, searching for the last trigger\_id and adding the tag...
