Mail and Messages do not search since upgrading to Ventura
I am having the same issue (on my M1 Max Macbook Pro running latest Ventura) as a number of users on this forum and have also tried the myriad of spotlight re-indexing fixes, rebuilding mailboxes and so forth provided on various sites such as Mac Observer. Ive been on a call with Apple Support and we tried all of the techniques they know, inc checking the drive with disk utility/reinstalling Ventura etc.
Some other tickets i found the same issue on ..
Mail App Search Woes (Ventura) - Apple Community (unresolved and old)
Mail app won't search emails properly and/or takes very long time (poster had to delete and create new user, not an attractive option)
Mail not searching (unresolved)
mail search does not give results (unresolved)
So this problem seems (a) reasonably widespread and (b) wickedly difficult to resolve!
I have the same issue mentioned in the first link whereby Apple Mail search is no longer showing as many options and no seaerch results (though occasionally one thread might appear after some time)
and the Activity window suggests its indexing but it never gets anywhere (after even a week of leaving the laptop on full time!)
Messages has no search at all and no indication as to why ...
Any help would be amazing - this really kills productivity.
