I have been walking through a lot of pages in internet but have not found any answer except one. However, the answer is not complete, so I will share my experience here.
This feature is very useful, especially to summarize the issues found during certain tests, where the tests are reported in a confluence page. I found that there are so many questions about this, but Atlassian seems does not want to bother with this request. I found one way to do this by the following tricks
Take one JIRA issue that related to the target confluence page (in this case, say it is GET-895) Find the global ID of a JIRA issue:
It will show the JSON like this:
Then take the globalId from there to search issue in JIRA
issue in issuesWithRemoteLinksByGlobalId("appId=662e1ccf-94da-3121-96ae-053d90587b29&pageId=105485659")
However, this morning I found out that the filter only works for a single user. So for example I report GET-001 and Denis report GET-002, the filter will show only JIRA tickets from me. In order to include Denis's report, we have to take one JIRA ticket from Denis, find the globalID and add the query into JQL. For example, the above query will be:
issue in issuesWithRemoteLinksByGlobalId("appId=662e1ccf-94da-3121-96ae-053d90587b29&pageId=105492363") or issue in issuesWithRemoteLinksByGlobalId("appId=662e1ccf-94da-3121-96ae-053d90587b29&pageId=105492386")
