I am telling you that according to the manual you can do that, and my experience matches the manual.

Quite simply, a Comma-separated text, like tags column will by definition ALWAYS split on commas, as the definition implies.
And a hierarchical column will ALWAYS create hierarchy subgroups splitting on periods.

And you have said that your copy of calibre is not doing so, although you have not said that the behavior when you try is the same behavior as the expected behavior when you use the wrong column type (as I explained in the previous two posts)... so for all I know your problem when (claim) you use the correct column type may be something completely different, which you have not told us about and we therefore cannot be expected to help with.

Of course, it is possible, though highly unlikely, that you are running a copy of calibre that has been sneakily modified for the express purpose of NOT doing so, and thereby confusing you... but failing that you are simply mistaken.


Would it help if I gave you a picture of me doing the thing you just told me is impossible?

One book. One column, of type "Comma-separated text, like tags, shown in the tag browser, listed in Preferences as being hierarchical. Two comma-separated tags, as specified above.
