I have seen that the way to query for a `labels` field that is missing a specific value is:
labels is EMPTY or labels not in ("x")
However, I have multiple label values that can be used, and this does not seem to work for that case. For example, if an issue can have any combination of 'label1`, 'label2`, and `label3`, I want to search for issues that are missing `label1`. Because there are actually many more than 3 possible labels, it isn't practical to test for all possible combinations.
Any suggestions?
