Redmine plugin to facilitate searching through archived projects.
Useful if you prefer to "Archive" rather than "Close" projects, to make all the open issues disappear. Injects a check box on search form "Include archived projects", which injects "?search_archived=1" parameter on any page, including search pages. This parameter will only get picked up for admin users.
Tested against Redmine 2.6, likely to work with 1.4 as well.
