How to make High Sierra find tags created with Sierra?
Under Sierra I used colour tags to mark files I wanted to access quickly. After upgrading to High Sierra, Finder is only finding some of those files. Most do not show up when I click one of the colour tags that are listed at the bottom of a Finder Window sidebar.
I have tried asking Siri - it gives the same results as I see when selecting a sidebar tag.
The only way to make the old Sierra tags findable seems to be to locate files by hand, delete the tag, then re-create it. Surely that wasn't intended?
Does anyone know how to make High Sierra find these files? Would it help to force Spotlight to re-index my files, and if so how would I do that?
I have not seen any other discussion/ question reporting this issue - is it just me? Thanks in advance if anyone can help.
