I am trying to create a filter to search for all issues that were ever assigned to me, even after the assignee is changed. I cant find the appropriate search parameters for this. Is it even possible in jira?
Check out the toolkit plugin https://studio.plugins.atlassian.com/wiki/display/JTOOL/JIRA+Toolkit+Plugin
It has a custom field 'Participant' which allows you to find all issues that you raised, were assigned to or commented on.
