I'm trying to create a filter to show all issues that were set to Resolved >= 1month prior to the current date. I've been using the 'resolutiondate' parameter, however it looks like this function is broken. Most of the time the search doesn't return any results (I know there are results for those searches) and other times, the results returned don't match the date and time range I've specified.
How do I use this term correctly?
