I am having a "moment". On one of my civicrms when I use the advanced search I can search mailings. On one of my other civicrm installations the mailings are not available to be searched - the accordian is short of the "mailings" tab. I'm assuming it is somewhere in the configuration but I cannot find it, nor can I find it in the user guide.
Can someone point me in the right direction.
Thank you!
