I tried below search for 2nd question but didn't work.

P.S: In my environment we parsed EventID as EventCode

| rest /services/saved/searches
| search is_scheduled=1 OR alert_type=1
| table title, actions
| mvexpand actions
| rex field=actions ".*EventCode=(?<EventCode>\d+).*"
| stats count by EventCode, title

Please help me..

| where count > 1
| sort -count
