(Scriptrunner) what’s the difference b/w “linkedissuesOf” and “linkedIssuesOfAll” in IssueFunction?

[Lance Wilson]

I’m trying to run a linked issue query for Scriptrunner that allows my  metrics  to see issues related to various projects.

the problem I’m facing is that I’m having to come up with every possible issue link  in my search and I want to know if that is possible in Scriptrunner? That way I don’t have to write complex code for every filter.

so far, what I had to do is type “IssueFunction in LinkedIssuesOf(Variable, {issue link type}) with compounded “Or” statements.

is there a shortcut for this where I can accurately include these issues?
