This is now two different Mac machines I'm experiencing this issue, one that was a fresh install. The first sign I notice of Spotlight breaking is that my flagged emails disappear. When I do a test search in Spotlight, I noticed it only shows results for bookmarks and the dictionary, nothing else, even though that keyphrase should have brought up results in my contacts, calendar, emails, etc. Rebuilding the index doesn't fix ****. If I reboot, my flagged emails return for five seconds then disappear again. Sometimes when I open Spotlight and input a key term there's a bar indicating that it's indexing. Being able to search and flag email is crucial for me and I am getting tired of Spotlight ****ing up my daily workflow. Anyone else noticing issues? I'm sick of this ****.
