is there a way to view all tickets an agent has worked on (not just the one that are currently assigned to them)? For example if Agent A worked on a tickett but could not resolve it and they assign it to someone else - how do I see ALL tickets that agent A worked on?
I'm glad you were able to use was in. That's definitely odd you weren't able to use assignee directly. Do me a favor and take a look at JRASERVER-28091 and see if that matches your scenario when trying to search using assignee was and if so please vote on the issue to add impact.
