TABLE key, summary, status
WHERE epic-key = [[E28416]]
I did try this option before and it also does not return any results.
To work with both, then you need to clarify some other info (for example: if all link cases are a real files)…
The actual link itself is a link to another note that might exist but it will not always exist as it might be a new link which i have not created the note for yet.
maybe you have more than one epic-key:: in each note (if a list/array of values per file, then you can’t use = (because equal means literally “equal”) - needs to use contains();
maybe there’s any syntax issue with the way you input your pair key:: value;
…
As a generic search for multiple cases, try WHERE contains(epic-key, "E28416") OR contains(epic-key, [[E28416]])
