What does "is epic of" mean?

[David Witherspoon]

I'm having trouble translating some of the scriptrunner extension commands into English (so I can really understand what they are doing).

For example, on one of our JIRA boards someone has created a quick filter like:

issueFunction in linkedIssuesOf("project=bob AND issuetype=epic AND ScrumTeam != SCRUM2", "is Epic of")

The Subquery part says "epics in project 'bob' not assigned to 'SCRUM2'. I don't understand the [link name] part. Since the Subquery is already looking for epics, then what does "is epic of" do in this case? [link name] is supposed to describe the way in which the issue is linked.

It's definitely doing something. If I run that query without "is epic of" I find about 100 issues. Adding it back, I get over 500. Why?

@David Witherspoonlinkedissuesof is going to return issues linked to your sub-query.  The "is Epic of" specifies which link the function will return issue for.

But is "is epic of" redundant, since the Subquery finds epics already?

It looks like you've got a custom field called "ScrumTeam" and one of the values available for it is "is Epic of"
