In one of our projects people worked with two labels that have different upper/losecase letters, but are equal otherwise (e.g. myLabel_1 , mylabel_1).
Now the trouble is that (for whatever reason) some people even added both labels to their issues.
I tried using
labels = myLabel_1 AND labels = mylabel_1
and Jira (Server) even suggests both labels as different ones. But when the search runs, it does not take the "AND".
From what I found, Jira accepts camelcase as a label and in the auto-completion of the JQL, but neglects camelcase when searching.
Has anyone faced this and found a solution that can be done from the UI or REST API? Or can give me a hint? I am not very fond of messing around directly in the database.
