Mail Search Not Working Big Sur 11.5.2 (M1 MBP 13)

[tangfj]

Mail search has stopped working for me which I think started happening after upgrading to 11.5.2... I tried all the stuff that came up in my searches including rebuilding spotlight and rebuilding inbox/etc... nothing has worked.

Anyone else having this issue and have any fixes?

UPDATE:
In case this helps anyone else I contacted Apple Support and they had me try this fix, which ultimately worked for me...

1. Quit mail app
2. Open the finder and use the menu bar up top to Go>Go to Folder
3. Then go to ~/Library/Metadata/CoreSpotlight
4. Highlight all items
5. Control click the highlighted items and then click New Folder with the Selected items
6. Open the mail app and let it alone for 24 hours
7. After 24 hours test search

I don't know what this did but it worked for me... all searches are working perfectly now and even my smart mailboxes are working 100% (whereas before they didn't work 100% of the time).
