JIRA / JQL: How to *negate* "status changed to closed by" in a JQL filter (so as to only look for issues *not* closed by user X)?

Question

Building on Filter issues by the user who closed them, how to modify this query to give issues not closed by user a and user b?

Answer 1

Use "AND NOT status changed BY" like so:

status changed BEFORE  endOfWeek('-1') AND NOT status changed BY membersOf("QA")

(cf. https://community.atlassian.com/t5/Jira-Software-questions/Search-for-issues-where-status-was-changed-by-other-members-than/qaq-p/761756)
