How to find test cases which are not linked to any Stories/Task/Sub-tasks?

Question

I'm trying to Query with

project=<ProjectName> AND issuetype=test AND key not in linkedIssues("Test-1",Test-2")

But it is showing me

Issue link type 'Test-2' could not be found in function 'linkedIssues'

Linkedissues answers "what is linked to this issue"? (With the option of specifying the type of link).  It does not "List everything linked to this list of issues"

You will need to use

and key not in linkedissues("test-1") and key not in linkedissues("test-2")
