How do I query for siblings of issues?

Question

I would like to create a list with issues and their siblings. How do I write the query?
I have tried PARENT=issueID, but I can't get it to work.

I would like some thing similar to:

Parent_Issue-XYZ

Child_issue-AAA
 Child_issue-BBB
 Child_issue-CCC

Parent_Issue-KLM

Child_Issue-EEE
 Child_Issue-FFF
...

Hi @Magnus Edlund,

If you are fine with a marketplace app, we have created an app to view your sibling issues and their description without loading the entire parent nor using the filter.

It is really a straight forward app which adds a new Other subtasks panel with descriptions.

Hi @Magnus Edlund ,

If you have the scriptrunner plugin, you can do something like this:

issueFunction in subtasksOf("issuekey = {{your ticket's parent key}}")

It looks like you want to search EPIC with their child stories and their child sub tasks. You can use following query to get the results by using the plugin : JQL Search Extensions for Jira & reports after installing the above plugin , please use following query it will return you all parents with their child's. issue in allIssuesInEpic(your parent issue id's which is epic id)
for example

issue in allIssuesInEpic(epic-12, epic-13) it will return all issues belongs to epic id 12 and 13 you can find more documentation here https://jqlsearchextensions.atlassian.net/wiki/spaces/SEARCH/pages/30497099/JQL+Reference+Server#JQLReference(Server)-AllIssuesInEpic(jql-queryorissuekey)
