We're using fixVersions which indicate the quarter in which the issue will be fixed and also the specific version. So, the issue can be label for instance Q1/2013, R185 for the first quarter of 2013 and release 185. What I would like to do is create a search for issues that are scheduled for Q1/2013, but don't have a specific version set, yet. If I filter fixVersion = "Q1/2013", I also get issues scheduled to R185 in the search results.
