I'm trying to filter my GitHub issues based on an OR filter of milestones. Specifically, I want to retrieve all issues that are in milestone X or milestone Y.
Things I've tried:
milestone:X,Y
milestone:"X","Y"
milestone:X milestone:Y
-no:milestone
(aka show me issues that have any milestone by way of not showing me issues with no milestones)
I'm using GitHub Enterprise so don't have the option of installing additional products.
Edit: Seems like per Can I search github labels with logical operator OR? searching labels by logical OR works (for issues), but the same syntax for milestones did nothing for me.
