How can JQL be constructed to show issues with no worklogs?

[Micheal Wall]

I'm looking for a bit of help. I'd like to apply a filter to look for issues that have no worklogs associated with them. I can see that there is a worklogDate field; however, according to Rovo, doing worklogDate is Empty is not guaranteed to work. The behavior of that is dependent on Jira version and is not considered stable. Indeed in my testing, that filter does not identify tasks that have no worklogs associated.

Does anyone have an example to quickly identify issues that do not yet have a single worklog associated with them?

Hi Michael,

You might try: timespent is empty

If you are using Jira Cloud, which you say you are, then Version should not be a factor.
