I am trying to figure out how to search issues with a status of "Backlog" within a date range. I've tried a number of different searches and they do not like searching by the status "Backlog". Below is one of my attempts that didn't work. I have been able to search by CHANGED TO "Backlog" or CHANGED FROM "Backlog", but that doesn't get me what I'm looking for. Any ideas?
project = OESUPPORT AND backlogDate >= "2018-01-01 00:00" and backlogDate <= "2018-01-31 00:00"
Error: "Field 'backlogDate' does not exist or you do not have permission to view it."
