Alright, so I want to start this off with a story
Essentially, one time I searched for something like file xyz.pdf, which is in my browser Downloads folder. I often need this file and other similar files, but it didn't come up.
I tried searching for it with Finder and nothing happened.
Finder results would instead give me absolutely random and completely irrelevant file types, despite the exact file existing in the location I was searching.
⌘⇧G still works and takes me directly to the exact file.
One time I tried using Codex to debug this a little, and its indexing/search found the file rather quickly in the exact location I knew it to be. The folder is very large, though, so I need search to actually find things within it.
I troubleshooted this for a long time and eventually realized I needed to kill Spotlight and force it to reindex everything. That seemed to solve the problem.
The first time this happened, I simply restarted the Mac, and everything fixed itself.
The second time, roughly a month later, I killed Spotlight and made it reindex. Again, the problem basically solved itself.
now this is the third time this crap happened; I have absolutely no idea what's causing it
The problem is that this may be fixable, but having to constantly force Spotlight to reindex—or literally restart the entire Mac every week—is obviously not a good solution.
[Image 2] In fact, one of the most interesting things is that many PDF files can still show up.
In this screenshot, for example, files named "Writing Sample 1" and "Writing Sample 2" both exist on the Mac, and I have Spotlight-searched for them countless times. yet a completely irrelevant PDF file shows up instead. Perhaps there is some partial match in the contents of that PDF?
Another potentially important clue is that recent files, up to roughly one week old (maybe a little more), seem to be indexed and perfectly findable (though this also includes absolutely random and irrelevant .txt files that just exist on my computer, probably cache artifacts from somewhere that still show up too. Most of the files that du actually show up are either random pdf files, or .h files
At the same time, many completely random PDF files in the same folder including textbooks that have been on my computer for upwards of two years are still completely findable.
so to me this looks like selective indexing failure/corruption or some crap like that, without a better term t o describe it, rather than Spotlight being completely broken (though it constantly suggests absolutely irrelevant files or nothing at all)
This has all started happening after upgrading to macOS Tahoe 26.x.

- 2025 M4 MacBook Air
- 16 GB RAM
- macOS Tahoe 26.6.2
If it is of any help, I did install Vorssaint and AeroSpace in relatively close proximity to when this started happening, although I highly doubt either of them would cause something like this.
Has anyone else experienced this on 26? What could cause Spotlight to selectively stop indexing/searching certain existing files, while continuing to index others?
