Is there a way to accomplish this?
The reason for this is I am trying to force spotlight to receive automatic updates when invisible files and folders are added/removed. This behavior I believe is a side effect of not indexing the meta-data (but I could be wrong). I came to this conclusion from this SO question.
Is the solution writing a mdimporter? Will it even work for invisible file types?
After some research, it seems there is no way to force indexing of invisible folders.
I am instead searching all folders and getting updates for all folders. (Still very fast if you are wondering)
