Tags in Finder not working reliably
I'm in Monterey 12.2 (latest). Finder Tags, which had worked perfectly for me for a long time, have begun behaving unreliably.
I have a set of files that I have assigned a tag to ("K-Misc Faves"). Hundreds of them.
I have a previously-created smart folder which is set to the search criteria "tags match K-Misc Faves" and this had, up until last week, always displayed my hundreds of files tagged this way.
Now, the smart folder only shows about 15 of them.
I can go and find the hundreds of files tagged with that tag; they are still tagged accordingly.
I tried to go and create a new smart folder with the same (or similar) criteria. This new smart folder only shows the same 15.
If I go and find a handful of my hundreds of tagged files, remove their tags, re-add their tags, then check my smart folder, YES they now show up.
In other words, some of the tagging might have gotten corrupted somehow, but I have no idea how. And there are too many files (and too many tags) to have to redo everything.
How did this get broken and how might I reset it?
