I want to use a hierachy classifier where some documents will have more
than one value.

For example, if I have countries, one document may have relate to the US,
another to the UK, and a third to both.

I will use a text file for the codes (eg 1st line could be NZ 1 New
Zealand, second line UK 2 United Kingdom etc in alphabetic order)

Should I have more than one document metadata item to store each of the
values (eg Country1, Country2 both metadata items)
or should I combine these (eg USA|UK - or should that be "USA"|"UK" ?) in a
single Country metadata item?

If I should use two metadata items, how do I configure the hierarchy using
both metadata values?

Thanks
