Syntax filters for Release Notes

[Adrian Szubert]

Dear Community

I am a fledgling Scrummy for my Team and for JIRA. I am taking care of our board and dashboards to make life easier (my own as well).

Recently we have started using Releases in Confluence to share them with the rest of the IT Department. Unfortunately, I can see a bit of behavior where validation on Release Notes is being workaround with ".", "NA", "N.A." etc., or left completely empty (and this is for specific issues). 

I would like to provide a filter where I can show all of those empty or not correctly provided Release Notes. Below you can find the syntax I have created: 

project = "MyProject" AND sprint in openSprints() AND status not in (Rejected, Duplicate) AND type not in (Epic, Task, Sub-task, Analysis, "Smoke Test Task") AND "Release Notes[Paragraph]" ~ "\"NA\"" ORDER BY key ASC, assignee ASC

My question: Is there a way to use "Release Notes[Paragraph]" either for the EMPTY field or multiple texts?

Looking forward to seeing your responses.
