Finder search problem with partial names - macOS 15.7

A couple of years ago, the Finder search was broken and required about three terminal commands to fix. (Although in my experience, the problem kept reoccurring.) That seems to have mostly been resolved but I stumbled on a problem last night involving partial file names. I could not remember the entire name of a folder, only part of it - the search did not find the folder.


[Example: filename was BobChuckMary - I remembered Mary but not BobChuck.]


I eventually found the folder manually - for a grin, I tried the search again with another folder in that subdirectory, again only using part of the name. This time it worked. But it still could not find the folder I was originally looking for despite being right in front of me in that same subdirectory. Clearly, the finder search can only find files using partial names irregularly.


I rebooted and nothing changed. I have not tried that previous terminal fix to get Spotlight to re-index. I might try that later, but something tells me that this won't fix it generally. It's a strange indexing error.


Anyone else see this? Maybe macOS 26 fixes but I have not taken the plunge yet.

It is important to use Spotlight reserved words to narrow your search. Spotlight strings are case-insensitive and to find a folder with Mary in the name, you would use:

kind:folder name:mary


I just tested this on macOS Tahoe 26.0 with a folder named BobChuckMary and it was the top hit when using the Finder menu bar 🔍 Spotlight tool with the preceding query in it.

In playing around with this, it almost seems like it's a field length problem. The file, or folder in that spawned the OP, can be found using the first part of its name - I did not think of trying that earlier. The total name length is longer than 10 characters. If I use the last few, as I was doing, it cannot find the file. I tried this with other files, folders, of similar length and got the same problem (not exhaustive at all).


Some files, folders, had more than one word in their names, such as "file dummy." If so, those could be found even if the total character length was too long, but the last component was short enough.


Just documenting what I saw this morning.

Well, as I said in the description, using Finder for the partial name search sometimes works, sometimes does not. I am not sure why narrowing the search would be better if the indexing is done properly, although it would obviously take less time. I tried your example from Finder using the partial name of the actual file that is at issue. Same result as before - the file was not found. [I was not aware of these reserved words for Spotlight, so that is useful information.]


As I said below, I am currently rebuilding Spotlight, so I will see what happens in the morning. I think I will need to submit a trouble report to Apple after that, my guess.

Well, as I said in the description, using Finder for the partial name search sometimes works, sometimes does not. Your reply has some useful information about Finder that I was not aware of but as with the other reply along the same lines, it did not change anything. Same result as before - the file was not found.


Rebuilding Spotlight also failed so I think I will need to submit a trouble report to Apple.

Yeah, the Finder searches seem to be very quick so in this case, it's a solution looking for a problem. If the search without the filters cannot find the file, I would not have expected filtering to help other than to speed up an already fast response. But I have seen stranger things so I tried it.

I have seen a lot of strange things over the years, so I try never to assume anything these days especially when it involves Apple who is focussed on bright & shiny sparkly new things and not on fixing the boring broken & buggy things.
