Only remove duplicates is a older ticket with a certian comment exists

[Symon Turner]

I have followed the excellent guide to de-duplicating tickets 

https://community.atlassian.com/t5/Jira-questions/How-to-avoid-duplicate-issues-being-created-by-an-external/qaq-p/1111836

However, I really only want to trigger depue if there is an older ticket with "acknowledged" in the comments but I am not sure how to do this.

Hello @Symon Turner 

Welcome to the Atlassian community.

You can search for issues that have specific text in a comment with this criteria:

comment ~ "acknowledged"

If you add that to the JQL in the Lookup Issues step, that should satisfy your requirement.
